Jules Jacobs

I'm a PhD student of Robbert Krebbers at Radboud University studying formal verification and programming languages, and working on deadlock freedom in collaboration with Stephanie Balzer.

Some of my favourite things are: type theory, parametricity, SSA as a dataflow lattice, generating functions & Kirchoff's matrix-tree theorem, differential forms & the Gauss-Bonnet theorem, star semirings, Lagrangian mechanics.
