I am a Postdoc Fellow affiliated with the ETH AI Center and the Medical Data Science group at ETH Zürich. My research focuses on causality, information theory, and multimodal learning to approach modern challenges in the medical and biological domain. I obtained my Master’s degree in Bioinformatics in 2016 and completed my PhD in Computer Science in 2021 at Saarland University. During my PhD, I was part of the Exploratory Data Analysis group affiliated with the CISPA Helmholtz Center for Information Security and the Max Planck Institute for Informatics.

For Students: If you are looking for a thesis/semester project, feel free to contact me. Open projects in the medical domain include time series classification & forecasting of blood glucose from multiple data sources or representation learning from multimodal data (see the projects I talk about here). Additionally, we can discuss projects related to mutual information estimation (see SDM'21, SDM'22), or causal discovery under weak assumptions (see, e.g. AAAI'21, UAI'21).
