Dear All, I would like to invite applications for a fully-funded PhD position in the School of Computer Science at the University of Birmingham, UK. Topics of interest include: * Syntax and semantics of type theory * Formalisation of mathematics in univalent foundations * Directed type theory * Algebraic specification of programming languages Students broadly interested in one of these fields of research, or a related field, are strongly encouraged to apply. Applicants should hold, or be about to obtain, a Masters or Bachelor degree in Computer Science or Mathematics. The PhD position is fully funded, covering tuition fees and a tax-free scholarship. Healthcare is provided. For further details please send me an email (b.a...@cs.bham.ac.uk) and see my website (https://benediktahrens.net). The theory group at Birmingham's School of Computer Science is very active, organising regular seminars and informal meetings, such as the YaMCATS category theory seminar, Midlands Graduate School, and Workshops on Univalent Mathematics. For more information see http://www.cs.bham.ac.uk/research/groupings/theory/. Information on how to apply is given on http://www.cs.bham.ac.uk/admissions/postgraduate-research/. However, interested candidates should contact me in the first instance. All the best, Benedikt Ahrens
