About

I am an assistant professor at Jagiellonian University (Poland). I have education in computer science (PhD), theoretical physics (PhD) and mathematics (MSc). I am also very interested in biology related topics. My most known contribution is ANS coding, which becomes the standard way our data is written. Here you can play with interactive simulators covering some of my interest.
