November 2016

Congratulations to David Pym who has been Prof David Pym (UCL Computer Science) has been appointed UCL’s University Liaison Director with the Alan Turing Institute (ATI).

Congratulations to Dr Alex Silva, Senior Lecturer at UCL Computer  Science  and member of the Programming Principles, Logic, and Verification Research Group who has been awarded on of the 2016 Philip Leverhulme Prizes, Philip Leverhulme Prizes. 

Check out this video that some of our students in the department made.  The video was released during UCL IEP programme and its aim is to introduce Engineering students (apart from Computer Science) to PPLV and get them excited about the subject.  It tries to explain the importance of the subject, the main research in the area and what is coming in the future. Also, it explains the core principle of 'Composition' and how it is used to create 100% correct proofs.

Well done Andrei Margeloiu, Cavan Black, Moiz Hassam, Sebastian-Valentin Burlacu and Suyash Kabra.
