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!

Great idea! Are there any plans to do this for other subfields as well?

Unfortunately, voting at a German embassy is not an option.

I'm extremely disappointed with the organization of the upcoming German election. Voting is a fundamental right, yet my ballot letter arrived too late in Toronto—now the fastest! delivery won't get it there by Monday, after the election. Unacceptable.

More 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.

Johannes Zenn @johanneszenn.bsky.social · Jan 31
We 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.
