Schimunek
Research Associate in the Computational and Biological Learning group at the University of Cambridge. I build data-efficient models for small-molecule discovery: few-shot prediction, generative modelling, and chemical reasoning models.

I work on machine learning for small-molecule discovery, with a focus on settings where data is scarce: predicting what a molecule does when only a handful of measurements exist. During my PhD I developed MHNfs, a few-shot model for bioactivity prediction. Since then I have worked on generative models for chemical and biological sequences, and on measuring how well language models reason about chemistry.
I joined the Computational and Biological Learning group in Cambridge in September 2026, working with José Miguel Hernández-Lobato. Before that I did my PhD and a postdoc at the Institute for Machine Learning at JKU Linz with Günter Klambauer and Sepp Hochreiter. I originally trained as a mathematics and physics teacher.
