Hello

My name is Joanna Ochremiak, I am a postdoctoral researcher at IMJ-PRG, Université Paris Diderot.




Research

I am mainly interested in applications of logic to the study of algorithms and complexity. Especially in the areas of constraint satisfaction problems, finite model theory, database theory & computation over infinite alphabets.

Upcoming

Logic and Learning workshop at the Alan Turing Institute

Proof Complexity Dagstuhl Seminar
