He is working as a PhD student in cooperation with the Continental AI Lab in Berlin, focusing on Bayesian Deep Learning methods for trajectory prediction in autonomous driving. Christian previously completed his M.Sc. in Systems Engineering and Technical Cybernetics at the OvGU Magdeburg in 2022.
Michael Stanley Smith Michael Stanley Smith // Mercator Fellow //

Michael is Mercator Fellow in our Emmy Noether Research Group. He holds the Chair of Management in Econometrics at Melbourne Business School since 2007. Being a leading researcher in Bayesian statistics and business analytics, his work has been published in top academic journals in statistics, econometrics, marketing and forecasting.
Florian Süßer Florian Süßer // PhD Student //

Florian joined the lab in July 2024 as a PhD student. Being a M. Sc. psychologist by education and having worked in e-commerce for 6 years, he now focuses on multilevel models, conformal prediction and Bayesian statistics.

Associate Members

Moussa Kassem Sbeyti Moussa Kassem Sbeyti // PhD Student //

Moussa joined our lab as an associated member in 2023. He is currently pursuing a PhD at the Technical University of Berlin while working as an AI Research Scientist at the Continental AI Lab in Berlin. His research primarily focuses on developing uncertainty-based automated labeling methods for 2D images in autonomous driving.

Guests

Daniel Liu Daniel Liu // Student Intern //

Daniel is joining the lab from June to August 2024 as a summer research intern. As a rising junior at Princeton University studying Mathematics and Computer Science, he is excited to be a part of the ongoing regression research conducted by members in the lab, This will include applying Bayesian statistics to penalized splines with Paul, and exploring Bayesian neural networks for counterfactual example generation with Tim.
Lucas Kock Lucas Kock // Postdoctoral Researcher //

Lucas completed his PhD studies in our group in March 2024 and then continued as postdoctoral researcher at the National University of Singapore (NUS). Generally, his work revolves around deep mixture modeling, distributional regression, and the realm of approximate Bayesian inference. He is now visiting our group in the beginning of September to work on a project on distributional copula regression.
