I received MSc in computer engineering (2004), and PhD in machine learning (2010) from the Budapest University of Technology and Economics. My main research interests are machine learning and artificial intelligence.

I like competitions. My program Tyson won the 2nd Hungarian Computer Go-moku Open Tournament (2005). I was the captain of The Ensemble team that finished second in the Netflix Prize competition (2009). I won third prize in the GE Flight Quest (2013).
