The Computer Science Graduate Society (CoGS) and Student Representation in the Department and Division


The Computer Science Graduate Society (CoGS) was founded in 2009 with the aim of providing a platform for the academic and social life of post-graduates in the department. We cover both student representation on several departmental and divisional committees as well as organization of a variety of social events. The latter provide an excellent opportunity for MSc students, DPhil students and post docs to mingle and catch up outside their research groups.

We run a large number of events to have something for everyone's taste. We kick off every term with a Pizza & Wine night, for newbies to have great start and everyone else to catch up after the holidays. Our annual dinner as part of the department's student conference in Trinity term is usually held in one of the colleges and gives a nice finish to a productive day. The weekly Wednesday Coffee & Cake runs throughout term and vacation time to make sure you get your mid-week caffeine and sugar fix. Other social events happen at irregular intervals throughout the term, examples include Geek Nights, pub trips, or board games nights. Last, but by no means least, we traditionally run our Summer BBQ in late July/August to celebrate the summer break and the sun with a delicious burger and a cold beer in the University Parks.

Student Representation

The members of the CoGS committee are also student representatives on the Joint Consultative Committee for Graduates (JCCG), which meets once per term. If you have any issues or concerns that you would like to be brought up in a JCCG meeting, please contact any of the people listed below. The CoGS president also attends various other committee meetings in the department as a graduate student representative, and represents the Computer Science department in meetings of MPLS division student reps.

Contact us

We love feedback - please email with comments or event suggestions.

Also, if you enjoy our events, why not give us a hand with one? Simply drop us an email with the one you like.

If you want to raise a matter for student representation, please contact your student representative (see below).


Kevin Milner
Apologetically Canadian, Kevin studied computer science at the University of Alberta before attending McGill University for an MSc in quantum information. He’s now working on security protocols for his DPhil with Cas Cremers through the CDT in Cyber Security (in between disrupting his officemates Chad and Katriel). He has a hobby for ‘everyday cybersecurity’, in the words of Andrew Martin—if you ever find yourself in need of opening a locked door in the RHB, he might just know where to find an Arduino that can help.

Martin Dehnel-Wild
Originally from South West London, Martin has run around the country (Dorset, The New Forest, Durham) before moving to Oxford to study a DPhil in Computer Security, also with Prof. Cas Cremers. Martin likes tea, good food, real ale, shiny computers, photography, and singing in Chapel Choirs.

Katriel Cohn-Gordon
Treasurer / General Dogsbody
Katriel grew up in Cambridge (the English one) and studied pure maths there, then crossed over to Oxford for a masters in computer science which ended up being about category theory and quantum mechanics. After that he left Oxford for industry as a data programmer in a hedge fund, but has now happily returned to student life with a focus on the formal analysis of security protocols, studying for his DPhil with Cas Cremers. He still enjoys fiddling with gadgets, reading the Internet, and -- when he can drag himself away from a computer -- fencing with the University team.

Vojtech Havlicek
DPhil Representative in Quantum Information and Foundations
My background is in theoretical physics, which I studied at Imperial College. I have keen interest in Quantum Computing. This brought me to start my PhD in theoretical physics at ETH Zurich last year, where I focused on problems related to Quantum Simulation. The scope of my project was unfortunately driven heavily towards ‘less-conceptual’ work which did not fit me very well and ended up being a strong enough reason to re-start my DPhil at Oxford this year.
Under the guidance of Dr. J. Barrett, I am focusing on foundational concepts in Quantum Theory and (Quantum) Computing, having strong interest in Foundations, Topological Quantum and Quantum Information in general.

Will Smith
DPhil Representative in Computational Biology
Chemist-turned-physicist-turned-biologist, Will is studying for his DPhil in the Computational Biology group, having snuck in from the Systems Biology DTC. As the 2014-15 GoGS president he focused on supplying industrial quantities of snacks to graduate students, a policy known as "Cake on Grand Scale" (CoGS). When he's not busy writing up or bothering bacteria (or both), Will enjoys sketching, poetry and long walks by the sea.

Ulrik Lyngs
DPhil representative from the SOCIAM group
A cognitive psychologist-turned-computer scientist, Ulrik spent three years in London as a producer for the world's largest philosophy festival, HowTheLightGetsIn, before returning to Oxford. When he's not working with Nigel Shadbolt and the rest of the'social machines' group on the future of technology design and data protection, he's playing the melodica, dancing salsa, or planning his next backpacking trip.

Elizabeth Phillips
Bio coming soon.

Matthew Smith
DPhil Representative from the CDT in Cyber Security
Matt comes from a town close to Manchester, England, which is arguably the best bit of the UK. He studied for an undergraduate masters degree in Computer Science at Warwick before starting in the Centre for Doctoral Training in Cyber Security. He is in his second year, which confusingly means he is a first year DPhil student. Outside of work, Matt enjoys sport (can talk about cycling for hours), photography and music.

Ahmet Kucuk
DPhil Representative in Security
You can generally find Ahmet at night, where if he is not working on his machine he is probably working on another one. Originally from Istanbul, Ahmet holds a degree in Computer Engineering and is a decent game programmer. Prior to Oxford he was working in ETH Zurich, and is now currently reading in the security group of Professor Andrew Martin. He is an organism that turns caffeine and pizza into software.

Alina Petrova
DPhil representative in Information Systems
Alina is from beautiful St. Petersburg, where she did her BA in Computational Linguistics. After quite some travelling and quite some studying in and around Europe, she earned her masters degree in Computational Logic and has now moved to Oxford to do a DPhil in Knowledge Representation. Alina loves learning foreign languages, good wine and city cycling. She is a huge fan of online education and will be happy to discuss what AI and ML might bring next - especially if you have some chocolate for her!

Prince Abudu
DPhil Representative in Software Engineering
Prince Abudu is an unabashed optimist and highly motivated youth leader who has an amazing commitment to excellence, along with firm determination to achieve greatness for the greater good. Prince graduated summa cum laude with a Bachelor of Science degree in Computer Science and as highest ranking scholar in the Department of Computer Science at Morehouse College, in Atlanta, Georgia, USA. Prince continues his education, as one of the two 2016 Rhodes Scholars selected from Zimbabwe. Prince's research interests are in the area of Sensor Networks and Embedded Systems focusing on the implementation of Machine Learning techniques in constrained environments. Prince is also Co-Founder and Chief Operating Officer for Emergination Africa (, an intercontinental youth-driven mentorship program operating in the US and in Zimbabwe.

Yuan Zhou
DPhil Representative in Probabilisitic Programming
Yuan is originally from Guangzhou, a fascinating city in the southern part of China. Before she came to Oxford, she did her Bachelor in Computer Science in National University of Defense Technology with distinction. Now she starts her DPhil in Probabilisitic Programming. Yuan loves making friends with people and learning different cultures and customs. She also enjoys playing the piano, doing some sports like swimming and discovering delicious foods!

Luke Geeson
MSc Representative
Hey I'm Luke, currently studying the MSc Computer Science with an interest in programming language theory and design.
