Robert Bamler
I am a Professor of Data Science and Machine Learning at University of
Tübingen, Germany, and a member of the Cluster
of Excellence "Machine Learning: New Perspectives for Science" and Tübingen AI Center.
My group performs research on scalable approximate Bayesian inference methods (especially variational methods) and on deep probabilistic models, with applications to neural data compression and natural sciences. Our research is at the intersection of probabilistic models, efficient inference algorithms, and novel powerful approximation techniques. The latter are often inspired by ideas from natural sciences due to my personal background in statistical physics.
Find out more about my group at our group website.
I joined University of Tübingen and the Cluster of Excellence for Machine Learning in November 2020. Before this, I was a postdoctoral scholar in the statistical machine learning group of UC Irvine lead by Stephan Mandt, and before that I was a machine learning researcher at Disney Research in Pittsburgh and Los Angeles. I received my PhD in theoretical statistical and quantum physics from University of Cologne in 2016, advised by Achim Rosch and with support from German Telekom Foundation.
