About me

Short bio: Vincent Fortuin is a tenure-track research group leader at Helmholtz AI in Munich, leading the group for Efficient Learning and Probabilistic Inference for Science (ELPIS). He is also a Branco Weiss Fellow. His research focuses on reliable and data-efficient AI approaches leveraging Bayesian deep learning, deep generative modeling, meta-learning, and PAC-Bayesian theory. Before that, he did his PhD in Machine Learning at ETH Zürich and was a Research Fellow at the University of Cambridge. He is a member of ELLIS, a regular reviewer for all major machine learning conferences, and a co-organizer of the Symposium on Advances in Approximate Bayesian Inference (AABI) and the ICBINB initiative.

Long bio: I am a tenure-track research group leader at Helmholtz AI in Munich, leading the group for Efficient Learning and Probabilistic Inference for Science (ELPIS). I am also a Branco Weiss Fellow and a member of ELLIS. Moreover, I am a regular reviewer for all major machine learning conferences, and a co-organizer of the Symposium on Advances in Approximate Bayesian Inference (AABI) and the ICBINB initiative. My research focuses on the interface between deep learning and probabilistic modeling. I am particularly keen to develop models that are more reliable and data-efficient, following the Bayesian paradigm. To this end, I am mostly trying to find better priors and more efficient inference techniques for Bayesian deep learning. Apart from that, I am also interested in generative AI, meta-learning, and PAC-Bayesian theory. My group is aiming for fundamental ML research, but with a clear motivation by real-world problems, especially in scientific and biomedical applications. If you are interested in joining the group, check out our open positions.

Before starting my group in Munich, I was a postdoctoral researcher at the University of Cambridge, working in the Machine Learning Group with Richard Turner. I was also a Research Fellow at St. John’s College, where I was mentored by Zoubin Ghahramani, and my research was supported by a Postdoc.Mobility Fellowship from the Swiss National Science Foundation.

Even before that, I did my undergraduate studies in Molecular Life Sciences at the University of Hamburg, where I worked on phylogeny inference for quickly mutating virus strains with Andrew Torda. I then went to ETH Zürich to study Computational Biology and Bioinformatics (in a joint program with the University of Zürich), with a focus on systems biology and machine learning. My master’s studies were suported by an ETH Excellence Scholarship. My master’s thesis was about the application of deep learning to gene regulatory network inference under supervision of Manfred Claassen, for which I received the Willi Studer Prize. During my master’s studies, I also spent some time in Jacob Hanna’s group at the Weizmann Institute of Science, working on multiomics data analysis in stem cell research. I then did my PhD in Computer Science at ETH Zürich under the supervision of Gunnar Rätsch and Andreas Krause, where I was a member of the Biomedical Informatics group as well as the ETH Center for the Foundations of Data Science. I was supported by a PhD fellowship from the Swiss Data Science Center and was also an ELLIS PhD student. Within my PhD studies, I visited and worked with Stephan Mandt at the University of California in Irvine and Richard Turner at the University of Cambridge. Moreover, I completed internships at Disney Research Zürich, working with Romann Weber on deep learning for natural language understanding in the Machine Intelligence and Data Science team, at Microsoft Research Cambridge, working with Katja Hofmann on uncertainty quantification in deep learning in the Game Intelligence team, and at Google Brain, working with Efi Kokiopoulou and Rodolphe Jenatton on uncertainty estimation and out-of-distribution detection in the Reliable Deep Learning team.

My Erdös–Bacon number is 6. To dive deeper into my academic heritage, check out my complete pedrigree (reaching all the way back to Ibn Sina), powered by the amazing Mathematics Genealogy Project.
