PhD in Biology at ETH Zurich — The Complete Guide

A doctoral degree in biology from ETH Zurich places you at the heart of one of the world’s most research-intensive scientific environments. This guide walks you through everything a prospective applicant needs to know: the Department of Biology’s research strengths, how the professor-driven Swiss admission system works, doctoral employment and salaries, the year-by-year structure of the doctorate, funding, life in Zurich, career outcomes, and practical tips for building a competitive application. Wherever official figures are concerned — deadlines, salary figures, eligibility cut-offs — this guide deliberately avoids stating fixed numbers, because ETH Zurich updates its regulations and scales regularly. Always verify current details on the official pages at ethz.ch and the Department of Biology’s own website before you apply.

1. Program Overview

A PhD in Biology at ETH Zurich is a research doctorate — a Dr. sc. ETH Zurich (Doctor of Sciences) degree — earned through several years of original, independent research conducted under the supervision of a professor in the Department of Biology (D-BIOL). Unlike taught doctoral programs in some countries, there is no large block of compulsory coursework at the start. The doctorate is fundamentally an apprenticeship in research: you join a laboratory group, define and execute a research project, and produce a dissertation that makes an original contribution to knowledge.

ETH Zurich consistently ranks among the world’s leading universities for the life sciences, and its Department of Biology is one of the largest and most diverse biology departments in Europe. Research spans the full spectrum of modern biology, from atomic-level structural biology and molecular systems to neurobiology, microbiology, ecology, and plant sciences. The department sits within a dense Swiss research ecosystem: ETH collaborates closely with the University of Zurich through the Life Sciences Zurich Graduate School, and doctoral candidates have access to shared core facilities for genomics, proteomics, advanced imaging, and high-performance computing.

A distinctive feature of the Swiss system — and of ETH in particular — is that doctoral candidates are typically employed by the university as research assistants on a formal employment contract, rather than being enrolled as students who pay tuition. This employment relationship comes with a salary set according to the Swiss National Science Foundation (SNSF) doctoral salary scales, social insurance coverage, and the full rights of an employee. Admission is professor-driven: you are accepted because a specific professor wants you in their group and has funding to employ you, not through a centralized graduate-school admissions committee alone. Understanding this principle is the single most important thing a prospective applicant can take away from this guide.

The typical duration of a doctorate in biology at ETH is in the range of four years, although the exact length varies with the project, the group, and the candidate’s progress. The degree culminates in a written dissertation and a doctoral examination (defense) conducted according to ETH’s doctoral regulations. Because ETH doctorates are highly regarded internationally, graduates go on to postdoctoral positions at leading institutions, careers in the Swiss and international biotech and pharmaceutical industries, science policy, and beyond.

2. Why ETH Zurich for Biology?

• World-class research standing. ETH Zurich is consistently ranked among the top universities in the world, and its life-sciences research output — measured by publications, citations, and international collaborations — places it in the global elite. Training in such an environment signals research excellence to future employers and collaborators.
• Doctoral candidates are paid employees. Rather than paying tuition, ETH biology PhD students are generally hired as research assistants with a salary tied to SNSF salary scales, plus Swiss social insurance. This employment model provides financial stability and professional standing from day one.
• Breadth of biological research. The Department of Biology covers molecular and structural biology, systems biology, biochemistry, microbiology, neurobiology, plant sciences, and more — all within one department and a single campus area. Interdisciplinary collaboration is the norm, not the exception.
• Outstanding shared infrastructure. Core facilities such as the Functional Genomics Center Zurich (a joint ETH–University of Zurich facility), advanced imaging centers, proteomics platforms, and ETH’s high-performance computing clusters give doctoral researchers access to equipment and expertise that few single laboratories could maintain alone.
• The Zurich life-sciences cluster. Zurich hosts ETH, the University of Zurich, university hospitals, and a dense network of biotech and pharmaceutical companies. This concentration creates exceptional opportunities for collaboration, seminars, and eventual employment — Switzerland’s life-sciences industry is one of the strongest in Europe.
• International, English-speaking research environment. Research groups at ETH are highly international, and English is the working language of science in the Department of Biology. While daily life in Zurich runs in German (the local Swiss German dialect), you can conduct your entire doctorate in English.
• The Life Sciences Zurich Graduate School. The joint doctoral program of ETH Zurich and the University of Zurich is one of the largest life-sciences graduate schools in Europe, offering structured training, courses, retreats, and networking across both universities — a major added benefit of doing your PhD in Zurich.
• Professor-driven admission rewards initiative. Because you apply to a specific group rather than a faceless committee, a strong, well-targeted application — one that shows genuine engagement with a professor’s published research — can open doors that a purely grades-based system might not.

3. Research Areas

The Department of Biology at ETH Zurich is organized around research groups led by individual professors, each pursuing independent research programs. What follows is an overview of the department’s major research strengths — the areas in which it is internationally recognized and where doctoral positions are most frequently available. Actual group offerings change as professors are hired or retire, so always check the department’s current research-group listings on the official ETH pages.

Molecular Biology

Molecular biology at ETH encompasses the study of the molecular machinery of the cell: gene expression and regulation, DNA replication and repair, chromatin biology, RNA biology, and the molecular basis of development and disease. Groups combine genetics, biochemistry, and cell biology with genome-wide approaches, working in model organisms as well as mammalian cell systems. Doctoral projects in this area often involve a blend of wet-lab experimentation and computational analysis, and they benefit from the department’s genomics and proteomics core facilities. If your background is in molecular life sciences, biochemistry, or genetics, this is the department’s broadest and most established research pillar.

Structural Biology

ETH’s structural biology research investigates the three-dimensional architecture of biomolecules — proteins, nucleic acids, and their complexes — and how structure determines function. Techniques include cryo-electron microscopy, X-ray crystallography, and NMR spectroscopy, supported by dedicated structural-biology infrastructure and shared imaging facilities such as the Scientific Center for Optical and Electron Microscopy. Doctoral candidates in this area typically combine experimental structure determination with biophysical and biochemical characterization. This is a strong choice for applicants with a background in biophysics, biochemistry, or physical chemistry who want to work at the interface of biology and physics.

Systems Biology

Systems biology at ETH takes a quantitative, integrative view of living systems: how networks of genes, proteins, and metabolites give rise to cellular behavior. Research programs combine mathematical modeling with high-throughput experimental data — transcriptomics, proteomics, metabolomics — to understand regulation, signaling, and metabolism. ETH is widely regarded as a pioneer in this field, and doctoral students here typically develop strong computational and data-analysis skills alongside experimental training. This area suits applicants comfortable with mathematics, statistics, and programming who want to apply quantitative thinking to biological questions.

Neuroscience and Neurobiology

Neurobiological research at ETH spans molecular and cellular neuroscience, neural circuits, and computational neuroscience. The department’s neuroscience groups work closely with the University of Zurich — including the joint Institute of Neuroinformatics — and with clinical partners at the university hospitals, creating a rich environment for research on the brain. Doctoral projects range from the molecular mechanisms of neural development and plasticity to systems-level studies of perception, learning, and behavior. Applicants from biology, physics, engineering, or computer science backgrounds all find entry points here.

Plant Sciences

Plant biology at ETH addresses fundamental questions in plant development, physiology, genetics, and plant–environment interactions, alongside applied research relevant to sustainable agriculture and food security. Research groups study everything from molecular signaling in plants to ecosystem-level processes, often in collaboration with ETH’s agricultural and environmental science departments. Switzerland’s strong tradition in plant science, combined with ETH’s experimental field facilities and controlled-environment infrastructure, makes this an attractive area for doctoral research with both basic and applied dimensions.

Microbiology and Infection Biology

Microbiology research at ETH covers bacterial physiology and genetics, microbial communities and the microbiome, host–pathogen interactions, and the molecular mechanisms of infectious disease. Groups work with bacterial, viral, and fungal systems, combining molecular genetics, cell biology, and increasingly computational approaches. Given the global importance of antimicrobial resistance and emerging infectious diseases, doctoral projects in this area are both scientifically exciting and societally relevant.

4. Program Structure & Timeline

The ETH doctorate in biology is not divided into rigid semesters of coursework. Instead, it follows a flexible, milestone-driven structure defined by ETH’s doctoral regulations and by the expectations of your supervising professor. The phases below describe the typical journey; individual experiences vary considerably.

Phase 1 — Orientation and Project Definition (roughly the first 6–12 months)

After your employment contract begins, you settle into the research group, complete any required safety and laboratory training, and work with your supervisor to define your doctoral project. This phase involves an intensive literature review, learning the group’s methods and experimental systems, and typically conducting pilot experiments. ETH’s doctoral regulations require the approval of a doctoral plan or research proposal within a defined period after the start of the doctorate — the exact timing and format are set out in the regulations of the Department of Biology, so check the official documentation. You will also identify your doctoral committee (the supervisor plus additional examiners or committee members as required by the regulations).

Phase 2 — Intensive Research (roughly years 2–3)

This is the core of the doctorate: full-time, independent research. You design and execute experiments, analyze data, troubleshoot, and progressively take ownership of the project. During this phase you are expected to present your work at group meetings and departmental seminars, attend conferences, and begin drafting manuscripts for publication. Peer-reviewed publications are the currency of the doctorate — while ETH regulations define the formal requirements for the dissertation, in practice most biology doctorates result in one or more first-author papers. Many candidates also participate in teaching or supervision of bachelor’s and master’s students, which is a normal part of the research-assistant role.

Phase 3 — Completion and Defense (roughly the final 6–12 months)

In the final phase, you write the dissertation — a monograph or a cumulative thesis based on published and submitted manuscripts, depending on departmental conventions — and prepare for the doctoral examination. The examination typically includes a public or semi-public presentation of the research followed by questioning from the examination committee. After successful completion, ETH awards the title of Doctor of Sciences (Dr. sc. ETH Zurich). Administrative steps, including the formal registration of the doctorate and the submission of the dissertation to the ETH library, are governed by the doctoral regulations; allow generous time for these formalities.

Timeline Overview

Timings are approximate and vary by project and group. Some doctorates are completed in under four years; others take longer, particularly when projects involve long experimental timelines or extensive method development. Discuss expected timelines openly with prospective supervisors before accepting a position.

5. Admission Requirements

Admission to the doctorate is governed by ETH Zurich’s doctoral regulations and by the specific requirements of the Department of Biology. The following are the typical expectations; exact criteria are published on the official ETH pages and may be updated, so verify before applying.

• A relevant master’s degree. ETH doctorates in biology normally require a master’s degree (or equivalent, such as a German-style Diplom) in biology, biochemistry, molecular life sciences, or a closely related field. For interdisciplinary groups (systems biology, neuroinformatics, biophysics), master’s degrees in physics, mathematics, computer science, or engineering may be accepted if the candidate’s background fits the group’s research. Bachelor’s-only applicants are generally not eligible for direct doctoral admission.
• Strong academic performance. ETH is highly competitive, and successful applicants typically have excellent grades, particularly in subjects relevant to their intended research area. There is no single published grade cut-off that applies universally; the supervising professor judges whether your academic record demonstrates the preparation needed for the project.
• A supervising professor willing to hire you. This is the decisive requirement. Admission is professor-driven: a faculty member of the Department of Biology must agree to supervise your doctorate and must have funding (from their own grants, an SNSF project, or another source) to employ you. Without a supervisor’s commitment, admission does not proceed.
• Research experience. Prior research experience — a master’s thesis, research internships, or undergraduate research projects — is effectively essential. Professors hire doctoral candidates to do research from day one, so evidence that you can design experiments, analyze data, and work independently carries great weight.
• English proficiency. The working language of research in the Department of Biology is English. You should be able to read the scientific literature, write manuscripts, and present your work fluently in English. Formal language-test requirements vary; check the department’s current admission pages for whether certificates are requested.
• Compliance with ETH doctoral regulations. Formal admission to the doctorate (registration as a doctoral student) follows ETH-wide regulations administered through the Doctoral Administration office. Your supervisor’s group will normally guide you through this process once a hiring decision is made.
• Visa and residence eligibility (for non-Swiss applicants). Non-Swiss nationals need the appropriate residence and work authorization. In practice, ETH’s HR and the hiring group assist with this process, and doctoral employment contracts generally provide the basis for a Swiss residence permit — but you should confirm current immigration rules for your nationality.

6. Application Process

There is no single centralized application portal or fixed annual deadline for most biology doctorates at ETH. Positions are advertised by individual professors when funding becomes available, and many are filled through direct applications. The process below reflects the standard route; always follow the instructions in the specific job advertisement or on the professor’s group page.

1. Identify professors whose research genuinely excites you. Browse the Department of Biology’s research-group directory on the official ETH website. Read recent papers from groups that interest you — not just the abstracts — and shortlist supervisors whose research direction aligns with your background and interests.
2. Watch for advertised positions. Open doctoral positions are typically advertised on the ETH job portal and sometimes on the group’s own website. Advertisements specify the project, required qualifications, the documents to submit, and the application deadline for that position. Apply exactly as instructed.
3. Prepare a targeted application dossier. A standard application includes a curriculum vitae, a motivation letter tailored to the specific group and project, copies of degree certificates and transcripts, and contact details for referees (typically two or three, often including your master’s thesis supervisor). Your motivation letter should demonstrate that you understand the group’s research and can articulate why you are a good fit — generic letters are easy to spot and rarely succeed.
4. Consider speculative applications. If a group does not advertise a position but its research is an excellent match for your profile, a concise, well-crafted speculative email to the professor — referencing their recent work and explaining what you could contribute — is an accepted practice in the Swiss system. Keep it brief, attach your CV, and do not mass-mail.
5. Interview. Shortlisted candidates are typically invited for an interview, often by video call first, sometimes followed by an on-site visit to Zurich. Expect to discuss your master’s thesis or prior research in depth, your understanding of the group’s work, and your motivation. You may also meet current group members.
6. Offer and contract. If the professor decides to hire you, you will receive an employment contract as a doctoral student / research assistant. The contract specifies the salary (per the applicable scale), the employment percentage, and the duration. Read it carefully and clarify any questions with HR before signing.
7. Formal doctoral registration. After hiring, you complete ETH’s formal admission to the doctorate through the Doctoral Administration, submitting the documents required by the doctoral regulations. Your supervisor and the group’s administrative staff will guide you through this step.
8. Relocation and onboarding. Arrange housing, register with the local authorities upon arrival in Zurich (mandatory for residents), open a Swiss bank account, and complete the group’s onboarding and safety training. ETH provides onboarding information for new doctoral employees — ask your group for the current resources.

7. Funding & Financial Support

One of the most attractive features of a biology PhD at ETH Zurich is that doctoral candidates are normally salaried employees, not fee-paying students. Understanding the funding landscape is essential for planning your application and your life in Zurich.

Doctoral employment contracts. Most biology doctoral candidates are hired as research assistants (often at a high employment percentage) on fixed-term contracts funded by the professor’s research grants — for example, projects financed by the Swiss National Science Foundation, EU framework programs, or other third-party funding. The salary is set according to the SNSF doctoral salary scales, which are standardized across Swiss institutions and increase with seniority. Because scales are revised periodically, this guide does not quote a fixed figure: consult the current SNSF salary scales and the ETH job advertisement for the position you are considering.

Fellowships and scholarships. In addition to employment contracts, some doctoral candidates are funded through competitive fellowships — for example, ETH’s own excellence fellowships, SNSF doc.CH grants in eligible fields, or international fellowship programs. Fellowship holders may have a different administrative status than employed research assistants, so clarify the terms (salary level, social insurance, duration) before accepting. If you are considering applying for an external fellowship to bring to ETH, discuss this with the prospective supervisor early, as the group must agree to host you.

Tuition and fees. Doctoral students at ETH pay modest semester fees rather than substantial tuition — but the exact amounts change, so check the current fee schedule on the official ETH pages. Compared with the salary, these fees are a small fraction of a doctoral employee’s income.

Cost of living in Zurich. Zurich is consistently ranked among the most expensive cities in the world. The doctoral salary is designed to support a single person living in Zurich, and thousands of doctoral candidates do so — but budgeting matters. The largest expense is housing: shared apartments (WGs, Wohngemeinschaften) are the norm among doctoral students and significantly reduce costs. Health insurance is mandatory in Switzerland and represents a significant monthly expense; doctoral employees are covered by Swiss social insurance through their employment, but basic health insurance must still be arranged individually (EU/EFTA nationals and others may have specific options — verify current rules). Groceries, public transport, and dining out are all pricey by international standards, while ETH-subsidized canteens (Mensa) offer affordable lunches on campus. Plan conservatively, build a small financial buffer before moving, and ask current doctoral students in your prospective group about realistic monthly budgets.

Additional support. Doctoral employees are generally entitled to funding for conference travel and research expenses through their group’s budget. ETH also offers support services for international researchers, including help with relocation, spouse/partner employment questions, and childcare options — inquire about current offerings during the hiring process.

8. Life in Zurich

The city. Zurich is Switzerland’s largest city and its economic and cultural engine — a compact, exceptionally well-organized metropolis of around 400,000 inhabitants (over a million in the metropolitan area) set between a lake and forested hills. It combines the career opportunities of a global financial and tech hub with an outstanding quality of life: clean streets, reliable public transport, lake swimming in summer, skiing within an hour in winter, and a vibrant cultural scene. For a biologist, the city’s density of research institutions — ETH, the University of Zurich, university hospitals, and a thriving biotech sector — means seminars, collaborations, and career options are always close at hand. The main trade-off is cost: Zurich’s quality comes at Swiss prices, so the budgeting advice in the funding section applies to daily life as well.

The campus. The Department of Biology is based primarily on ETH’s Hönggerberg campus, a modern science campus on a hill above the city with panoramic views of the Alps. Hönggerberg hosts state-of-the-art laboratory buildings, lecture halls, the campus Mensa, sports facilities, and student housing. It is connected to the city center and the main ETH Zentrum campus by frequent public transport. Campus life is active, with student associations, sports clubs, and departmental social events — and the international doctoral community means you will quickly find peers from around the world.

Housing. Finding housing is the single biggest practical challenge for newcomers. Zurich’s rental market is tight, and affordable rooms go fast. Start searching as soon as you have a signed contract: the most common platforms for shared flats and rooms are well known locally (ask your group for current recommendations), and ETH-affiliated student housing organizations offer rooms specifically for students and doctoral candidates, though waiting lists can be long. Shared apartments (WGs) are the standard solution for doctoral students — expect to attend viewings and introduce yourself to potential flatmates. Budget generously for the first months, as deposits and initial costs add up. Temporary accommodation for the first weeks (a sublet or short-stay room) is a sensible strategy while you search for something permanent.

Language and integration. Research runs in English, but daily life — rental contracts, administrative letters, small talk with neighbors — runs in German (and the local Swiss German dialect). Learning German, even to a basic conversational level, pays off enormously in quality of life and is worth starting before you arrive. ETH and the city offer German courses for internationals; check current offerings upon arrival.

9. Career Outcomes

An ETH Zurich doctorate in biology is a strong career credential in Switzerland and internationally. The most common trajectory is a postdoctoral research position — many graduates move to leading laboratories in the US, UK, or elsewhere in Europe, and ETH’s reputation opens those doors. The quantitative and interdisciplinary training characteristic of ETH (particularly in systems biology, structural biology, and computational areas) is highly valued by postdoc advisors worldwide.

Beyond academia, Switzerland’s life-sciences industry is a major employer of ETH biology PhDs. The Basel–Zurich corridor hosts global pharmaceutical companies, a dense biotech startup scene, and contract-research organizations; roles in R&D, medical affairs, regulatory affairs, and business development are natural destinations. The analytical, project-management, and communication skills developed during a doctorate transfer well to consulting, data science, science policy, patent law (often via additional qualification), science communication, and roles in international organizations based in nearby Geneva.

ETH’s career services and the alumni network provide structured support — CV workshops, industry contacts, and career fairs — and the Life Sciences Zurich network keeps graduates connected to the local ecosystem. As with any doctorate, outcomes depend heavily on what you do during the PhD: publications, conference visibility, teaching experience, internships, and networking all shape your options. Start thinking about your post-PhD direction in your second or third year, not in the final months.

10. Peer Comparison

How does a biology PhD at ETH Zurich compare with similar options? The table below sketches six leading programs. Funding models and admission styles differ markedly between the Swiss employment model and the stipend or studentship models common elsewhere — a difference that affects your finances, your legal status, and your day-to-day independence. Details change, so verify current terms on each institution’s official pages.

The Swiss model’s defining advantage is the employment contract: a real salary, pension contributions, and employee protections. Its defining demand is that you must convince an individual professor to hire you — there is no safety net of a centralized cohort admission. Choose based on research fit first, funding model second, and location third.

11. Tips for Applicants

1. Lead with research fit, not prestige. Professors hire the candidate who can advance their research program. Your entire application should answer one question: why are you the right person for this group’s current research direction? Cite their recent papers specifically.
2. Read at least three recent papers from each target group. This is non-negotiable. You cannot write a convincing motivation letter — or survive an interview — without understanding what the group actually does, which methods they use, and where the open questions are.
3. Make your master’s thesis the centerpiece. Your thesis is the strongest evidence of your research ability. Describe the question, your independent contribution, the methods you mastered, and what you learned — concisely, in your CV and letter, and in depth if interviewed.
4. Tailor every application. A generic letter sent to ten professors will underperform one deeply tailored letter. Mention the group’s specific projects, explain which skills you bring to them, and propose — briefly — how you see yourself contributing.
5. Choose referees who have seen you do research. A detailed letter from your master’s thesis supervisor outweighs a vague letter from a famous name. Brief your referees on the position so their letters can speak to your fit.
6. Apply to advertised positions promptly and completely. Follow the advertisement’s instructions exactly — required documents, format, deadline. Incomplete or late applications are routinely discarded without review.
7. Use speculative applications strategically. If no position is advertised but the fit is exceptional, send a short, specific email to the professor with your CV attached. One thoughtful speculative application beats ten generic ones; never mass-mail.
8. Prepare for a technical interview. Expect to present your previous research (often as a short talk), defend your methodological choices, and discuss the group’s papers critically. Prepare thoughtful questions about the project — interviews are two-way.
9. Clarify funding, contract terms, and expectations before accepting. Ask about the employment percentage, contract duration and renewal conditions, the salary scale applied, teaching obligations, and the group’s expectations regarding publications and working hours.
10. Start German early and budget for Zurich realistically. Even basic German transforms daily life, and Zurich’s costs surprise many newcomers. Talk to current doctoral students about real monthly budgets before you move.
11. Keep records and verify everything officially. Save every advertisement, contract draft, and email. And before any final decision, confirm requirements, fees, and deadlines on the official ETH pages — never rely solely on third-party guides, including this one.

12. Frequently Asked Questions

Do I need a master’s degree to apply for a biology PhD at ETH Zurich?
Typically, yes. ETH doctorates in biology normally require a master’s degree or equivalent in a relevant field. Applicants with only a bachelor’s degree are generally not eligible for direct doctoral admission. Verify the current requirements in the Department of Biology’s doctoral regulations.

Is there a central application deadline?
Generally, no. Most positions are advertised by individual professors as funding becomes available, each with its own deadline. Some structured programs or fellowship calls have fixed rounds, so check the specific advertisement or program page.

How do I find open PhD positions?
Check the ETH job portal, the Department of Biology’s research-group pages, and individual professors’ websites. Many positions are also filled through speculative applications, so contacting a professor directly is an accepted route.

Are PhD students at ETH paid?
In most cases, yes. Doctoral candidates in biology are typically employed as research assistants on a formal contract, with salaries based on the Swiss National Science Foundation (SNSF) doctoral salary scales. Confirm the exact terms in your contract and the job advertisement.

Do I have to pay tuition?
Doctoral students pay modest semester fees rather than large tuition fees, but the amounts change over time. Check ETH’s current fee schedule on the official website.

What language is the PhD conducted in?
English is the working language of research in the Department of Biology — lab work, seminars, manuscripts, and the dissertation are all normally in English. German is useful for daily life in Zurich but is not typically required for the doctorate itself.

How long does the PhD take?
The typical range is around four years, but the actual duration varies with the project, the group, and individual progress. Discuss expected timelines with your prospective supervisor.

Can I apply if my master’s is in physics, computer science, or engineering?
For interdisciplinary groups — systems biology, structural biology, neuroinformatics, computational neuroscience — such backgrounds are often welcome and sometimes preferred. For classical molecular or cell biology groups, a life-sciences background is usually expected. The professor decides based on fit.

It is the joint doctoral program of ETH Zurich and the University of Zurich, and one of the largest life-sciences graduate schools in Europe. It offers courses, retreats, and networking across both universities, complementing the research training in your group.

Do I need to speak German to be admitted?
No — admission and the doctorate itself run in English. However, learning German substantially improves your daily life in Zurich, from housing to administration to social integration.

How competitive is admission?
Highly competitive. ETH Zurich attracts applicants from around the world, and professors hire only when they have funding and a strong candidate. A strong academic record, relevant research experience, and a well-targeted application are essential. ETH does not publish a single overall acceptance rate for biology doctorates.

Will ETH help with my visa and residence permit?
Hiring groups and ETH’s HR typically support international doctoral employees with the immigration process, and the employment contract generally provides the basis for a Swiss residence permit. Immigration rules depend on your nationality, so verify current requirements early.

Can I do a PhD part-time or remotely?
Doctoral positions in experimental biology are normally full-time, on-site roles — laboratory research cannot be done remotely. Arrangements vary by group and project; discuss any specific needs directly with the prospective supervisor.

What degree title will I receive?
Successful candidates are awarded the ETH doctorate in the sciences — the Dr. sc. ETH Zurich title (in the natural sciences typically Dr. sc. nat. ETH Zurich). Confirm the exact title with the doctoral regulations current at the time of your admission.

Is Zurich affordable on a doctoral salary?
The doctoral salary is designed to support living in Zurich, and thousands of doctoral candidates manage it — most by sharing apartments and budgeting carefully. Zurich is nevertheless one of the world’s most expensive cities, so plan conservatively and build a financial buffer before relocating.

When should I start applying?
Because hiring is continuous and professor-driven, there is no single season. Start monitoring advertised positions and preparing speculative applications several months before your intended start date, and allow time for interviews, contracts, and — for non-Swiss applicants — immigration formalities.
