I am a postdoc in the Department of Logic in the Institute of Philosophy at the Czech Academy of Sciences in Prague, currently (2017--2020) funded by a grant from the Czech Science Foundation (GAČR). Before becoming a postdoc in Prague I wrote a PhD dissertation, Categories and Logical Syntax (PDF), at Leiden University under the supervision of Göran Sundholm. 

My main research interests are in the philosophy and history of logic and mathematics. I am especially interested in Martin-Löf's type theory and the philosophy connected therewith, as well as in the works of Frege, Husserl, Carnap, Dedekind, etc.
