Research Associates (Post-Docs)

I am always happy to receive applications from strong candidates.


A strong publication record including top conferences or journals, for instance IACR conferences such as ASIACRYPT, CRYPTO and EUROCRYPT, or other relevant A-ranked conferences such as CCS, Oakland, USENIX, etc. (see here for conference rankings).

How to apply

Currently no openings, but feel free to send me an e-mail to enquire about future oportunities. I prefer not to click on attachments, so instead of sending a CV, please include a link to your Google Scholar profile or DBLP page.

PhD students

I am happy to receive applications from students with an interest in cryptography. Please see below for the type of student I am looking for and how to apply.


BSc or MSc in Mathematics, Computer Science or related discipline with top marks. Applicants from universities in the UK should have marks well above First/Distinction level.

Good communication skills; especially in written English.

Research area

I am interested in building cryptographic schemes and mathematically proving that they are secure. I have worked on pairing-based cryptography, zero-knowledge proofs, internet voting and mix-nets, signatures, and public-key encryption. My publications can be found on my homepage. You should take a look at a few of them before applying to check that our research interests match.

If we do not match, maybe some of my colleagues working in other areas of cryptography and information security will be suitable advisors for you. Please look at the members of our Academic Centre of Excellence in Cyber Security Research to find a potential advisor that matches your research interests.


I do not currently have funding for PhD students but if you are a British citizen there are some options we can pursue including departmental funding or a PhD in security science UCL SECReT. It is hard to get funding for EU and Overseas citizens. If you apply as an Overseas student I expect you to be self-funded including both cost of living and UCL fees for overseas PhD students.


You cannot apply by e-mail, but if you have concrete questions please feel free to send me an e-mail before applying. When you e-mail me please briefly state citizenship, degree, GPA and awarding university in the main body of the e-mail so that I can quickly check that you meet the qualifications listed above.

I usually do not click on attachments, so please do not attach a CV to your e-mail.

How to apply

Applications can be made through the online system specifying Computer Science as the department and 'Jens Groth' as the supervisor.

An application should include transcripts from BSc/MSc degrees and other relevant information, e.g., work experience, awards, etc. You will be asked to submit a personal statement, which you can use to describe your academic and personal skills and experience and the reason you are interested in doing a PhD in cryptography.

Visiting PhD students

If you are a PhD student elsewhere and want to visit UCL for a few months the same criteria as described above apply. You will have to pay UCL's fees for PhD students at a pro-rata rate for the time you are visiting. To apply, use the online form for regular PhD students specifying the duration in your application.

MSc Students

University College London offers an MSc in Information Security. Please go to for more information and instructions on how to apply.

Summer Internships

University College London does not offer internships.
