I'm a Post-Doc and 50%-time lecturer at I.Kant Baltic Federal University at the Lab "Mathematical methods in information security".

My research interests include practical and theoretical cryptanalysis of lattice-based primitives. I also like to apply quantum techniques to speed up cryptanalytic algroithms for solving problems that underlie lattice- and code-based schemes.

I received my PhD from Ruhr University Bochum at the Chair of Cryptology and IT Secturity, advised by Prof. Dr. Alexander May. Then I was a PostDoc at ENS Lyon in AriC team supervised by Prof. Dr. Damien Stehlé.
