About Me

Who Am I?

I am an assistant professor at Czech Technical University in Prague, working in the fields of Computer Vision and Algebraic Geometry. My research is focused on algebraic methods for solving systems of polynomial equations with applications in camera geometry estimation and robotics. Recently I received a GAČR JUNIOR STAR 5-year grant to support my own research team of 3 PhD students and 2 Postdocs working on the topic of combining learning-based and algebraic approaches for camera geometry estimation.

Recipient of a GAČR JUNIOR STAR grant December 2021

Project Title: New generation of camera geometry solvers ,
Open PhD and PostDoc Positions (Topic: Combining Learning-based and Algebraic Approaches for Camera Geometry Estimation).

JUNIOR STAR grants are intended for excellent scientists in their early careers. The 5-year project allows them to receive up to CZK 25 million and gives them an opportunity to attain scientific independence or even start their own research team, which can bring new areas of research into Czech science.
