I am currently a Postdoctoral Researcher at the Faculty of Mathematics and Physics at the University of Ljubljana.
My research is in programming language theory, where I am particularly interested in dependent and refinement types,
 computational effects (in particular, algebraic effects and effect handlers),
 programming languages that include the above,
 the use of such languages for writing verified software, and
 the (category theoretic) semantics of such languages.
