# Vojtech Kaluza

Welcome to the home page of Vojtěch Kaluža. I am currently a fourth-year Ph.D. student of Computer Science at Department of Applied Mathematics, Faculty of Mathematics and Physics, Charles University in Prague, Czech Republic.

My current supervisor is RNDr. Martin Tancer, Ph.D. My former supervisor was prof. RNDr. Jiří Matoušek, DrSc.

My research interests include graphs on surfaces and discrete problems in connection with Lipschitz analysis and geometry of metric spaces.
