I've been waiting some years to make this joke and now it’s real:
I conned somebody into giving me a faculty job!
I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math
and I'm recruiting PhD students 🤗

Want to get started with theoretical analysis of probabilistic decision-making algos (bandits, BO, planning, etc.), but don't know where to start? Existing literature too dense to parse?
arxiv.org/abs/2508.21620
I've written a self-contained introductory monograph on this!

20.02.2025 14:46 — 👍 3 🔁 0 💬 2 📌 0More generally, we believe that the variational expectation maximization algorithm can be a useful tool for many physico-chemical prediction problems since it balances structure-based and representation-learning based predictions by weighing of their respective uncertainties.
31.01.2025 14:45 — 👍 0 🔁 0 💬 0 📌 0We extend a probabilistic matrix factorization method (Jirasek et al., 2020) by learning priors from the chemical structure of mixture components utilizing graph neural networks and the variational expectation maximization algorithm which significantly improves the predictive accuracy over the SOTA.
31.01.2025 14:45 — 👍 0 🔁 0 💬 1 📌 0Predicting the physico-chemical properties of pure substances and mixtures is a central task in
thermodynamics. We propose a method for combining molecular descriptors with representation learning for the prediction of activity coefficients of binary liquid mixtures at infinite dilution.
I am happy to share that we (finally!) took the time to publish parts of my Master's thesis as a paper (pubs.rsc.org/en/content/a...). Huge thanks to Dominik Gond, Fabian Jirasek and Robert Bamler. Check it out if you are interested in applications of machine learning to chemical engineering!
