I travel the world and collaborate with smart people all over the globe. I’m grateful that I spent a year as a full-time researcher at UPenn, one of the US Ivy League institutions. Currently, I work at 九州大学, one of the famous Japanese “Imperial” universities. Here are all my academic “homes”:


Academia gives me the opportunity to dive into topics I find really interesting. My research focuses on supporting teachers and students through automated analysis of learning data.


You can find my papers on Google Scholar and GitHub. I have experience in presenting my work at top-tier conferences in the USA, Europe, and Asia, including ACM SIGCSE.


I actively participated in the European Union pilot CyberSec4Europe and contributed to open-source projects for supporting cybersecurity training.


My goal is to offer interesting and valuable classes on data science, Python, and cyber-security. I received highly positive feedback and a university-wide award for the best teacher.

Student mentoring

I really enjoy advising students and helping them with their projects! So far, I supervised 14 bachelor and master theses. For the currently available topics, see the lab website.

YouTube math videos

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


“Valdemar always comes up with new ideas out of the box and strives to deliver outstanding performance and high quality solutions.”

Jakub Tomiš, entrepreneur and my former teacher

“The best tutor I ever had. Fair, always perfectly prepared. Friendly approach, kind, charismatic. I looked forward to every single class.”

Anonymous feedback from Software Engineering classes

“Individual approach. The lessons are not generic or boring, he creates extra activities. Comprehensible explanations. Fun classes.”

Anonymous feedback from programming classes

“Your videos saved me. Your explanations are great. I often don't get it in my math classes, but your videos made me understand right away.”

Ema Černáková, comment on my math video on YouTube

“It was fun, you created a perfect atmosphere and I learned a lot. I'll start studying computing at home, too. Thank you, you're great.”

About me


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, including jazz, fusion, grunge, art rock, and pop.


Exploring new places is fascinating. I visited 30 countries on 4 continents (Europe, North and South America, and Asia), but there are still many places on the bucket list. This website features pictures from my travels. There's more on my Instagram.


I work out regularly at the gym and used to do recreational swimming and boxing. During summer, I enjoy hikes in nature, but I don't do winter sports – instead, you'd find me playing board games (such as Imperial Assault) with friends.


I love watching movies; my favorite director is Christopher Nolan. I'm also a fan of stand-up comedy (Ricky Gervais, Bill Burr, Louis CK) and hard-hitting humor like South Park. Also, I find it really relaxing to watch random YouTube videos.
