### Research interests

The unifying theme of my research is **theorem proving**. I have been working on:

- Correctness of
**qualitative spatio-temporal reasoning** - Correctness of
**origami geometric constructions**

Proofs of correctness is based on algebraic methods (e.g. Groebner Basis, CAD) and interactive theorem proving (i.e. proof assistant Isabelle/HOL).

### Tools & libraries

- Computational origami system Eos (package and tutorial)
- Formalization of Allen's calculus (Isabelle/HOL theory file)
