Jan Hermann
Computational chemist and physicist by training️, who got later hooked on machine learning, and now enjoys integrating deep learning into quantum chemistry. I was born and raised in Český Krumlov, moved for university to Prague, and later for a Phd to Berlin, where I now live with my wife and our two kids. I work at Microsoft in AI for Science.
