I work at NORMENT (Norwegian Centre for Mental Disorders Research) at UiO Faculty of Medicine. We study Genetics of Psychiatric Disorders, identifying rare genetic variants or variation in gene expression in order to uncover hidden heritability of Schizophrenia and other mental disorders.

I have background in mathematics and machine learning. My PhD thesis is "Symmetry and randomizations in combinatorial theory of generalization ability" (Moscow Institute of Physics and Technology, 2013). I also have few years of experience in building industrial software. I worked on Search Engine for Sharepoint (Microsoft, 2010-2013), and on Petrel E&P Software Platform for seismic to simulation reservoir engineering (Schlumberger, 2014-2016).

My hobbies are cycling, skiing, hiking, and more cycling.
