based in Zürich / Warsaw · open for research collaborations

I’m an MSc Computer Science student majoring in Machine Intelligence at ETH Zürich, working on the safety of generative models. I collaborate with Anna Hedström at the ETH AI Center and Bartłomiej Twardowski at Research Institute IDEAS in Warsaw, where I previously worked as a Research Assistant and an AI Research Intern.

Before ETH I was a research software engineer in Przemysław Biecek’s MI²AI group. I built two open-source libraries, meteors for explaining hyperspectral imagery and SerolyzeR for serological data, and I ran the group’s small bare-metal GPU cluster hosting research demos, for instance ChestChecker.

I like understanding how things actually work, and I have a lot of fun doing it.
