We're delighted to publish ten PhD abstracts in this round. Topics range from types to tests, from synthesis to software engineering, from datatypes to differentiation. Have a look!

You can't read "A survey of graphical languages for monoidal categories" by Peter Selinger and then not post the impressive diagram at the end!

The School of Computing at the University of Kent has a PhD scholarship available, and the deadline to apply is February 15th. We're especially interested in students interested in programming languages, compilers, and systems! www.kent.ac.uk/scholarships...

The University of Nottingham School of Computer Science just opened applications for 10 fully funded PhD studentships. For people interested in functional programming, category theory, type theory and other areas of interest to the FP Lab, please see here: people.cs.nott.ac.uk/pszgmh/10-ph...
