Research

I am a doctoral student in the group of Prof. Jenny Thomas at UCL, currently working on the CHIPS experiment. I am also a researcher at Institute of Experimental & Applied Physics at CTU Prague, taking part (among others) in the ATLAS experiment at CERN and the Medipix3 Collaboration. The aim of my research is to better understand spatially or time-related datasets, usually originating from high energy physics experiments, using machine learning methods.

Previously, I obtained two master’s degrees in Computer Science. One from Charles University specialized in software systems, and other from Czech Technical University specialized in artificial intelligence (with minor in computer vision).

My ORCID is 0000-0003-4306-0209. I also have a GitHub account. Below you can find a complete list of my published works and other relevant materials.
