Research

I am a postdoc in the Penn Center for Learning Analytics at University of Pennsylvania. I completed my Ph.D. in the Cybersecurity lab at Masaryk University. My research focuses on supporting teachers and students through automated analysis of learning data.

Publications

You can find my papers on Google Scholar and GitHub. My Ph.D. thesis, supervised by Pavel Čeleda and Jan Vykopal, is publicly available as well. I have experience in presenting my work at top-tier conferences in the USA and Europe, including ACM SIGCSE.

Projects

I actively participated in the European Union Horizon 2020 pilot CyberSec4Europe, as well as the Czech national cybersecurity excellence center. I was also a contributor to the open-source KYPO Cyber Range Platform and the associated projects.

Teaching

I co-teach an Educational data mining course. In the past, I helped teach cybersecurity, Python, and workshops for high schools. My goal is to offer interesting and valuable classes. I received highly positive feedback, including a university-wide award for the best teacher.

Student mentoring

I really enjoy advising students and supervising their theses and projects! So far, I supervised 13 bachelor and master theses. The current PCLA projects are listed here. The currently available topics of CYBERSEC are found on the lab website.

Educational videos

Apart from in-person classes, I created mathematical educational videos in my own project Elea: Teach yourself math and also for the company Datakabinet that provides teaching materials to thousands of schools.

About me

Music

I played electric guitar in my art-rock band in high school. We had three shows, so it was a big deal! My teacher was an excellent musician Martin Novák from the band Sto Múch. I enjoy many different genres of music, mainly including jazz, fusion, grunge, art rock, and pop.

Movies

I love watching movies and TV shows. My favorites include anything from Christopher Nolan, most works by Quentin Tarantino and Stanley Kubrick, and, of course, Star Wars. I'm also a fan of stand-up comedy (Ricky Gervais, Bill Burr, Louis CK) and stuff like South Park.

Travelling

I visited 25 countries on 3 continents (Europe, North America, and Asia), but there are still a lot of places on the bucket list! This website features a few pictures from my travels.

Besides these things, I also exercise and used to do recreational swimming and boxing. During summer, I enjoy hikes in nature, and during winter, you'd find me playing board games with friends. I also like reading and attending cultural events (concerts, art exhibitions, museums).
