Overview

Welcome! On this web page, I give an overview over my research and background. I'm a research scientist at Bosch Center for Artificial Intelligence. I hold a doctorate in computer science done at Max Planck Institute for Intelligent Systems, and a diplom in mathematics from Heidelberg University with philosophy as a minor subject.

Research scope: I conduct research broadly in the areas of machine learning and multiagent systems, often including theoretical guarantees, validation, statistics, dynamical systems and interpretability of models. Currently I am focusing on imitation learning and data-driven realistic simulations. Previously, I also worked in the areas of causal inference and mathematical logic.

Selected publications:

1. Fail-Safe Adversarial Generative Imitation Learning. (2022). TMLR.
2. Learning game-theoretic models of multiagent trajectories using implicit layers. (2021). AAAI.
3. Coordinating users of shared facilities via data-driven predictive assistants and game theory. (2019). UAI. [Slides.]

Transfer: I also work on the multi-stakeholder problem of co-evolving innovative research with applications that are relevant for society. In particular, I consider applications in the areas of safe automated driving and resource-efficient sharing economy.

• On Learning the Tail Quantiles of Driving Behavior Distributions via Quantile Regression and Flows:
  

  Towards better testing the safety of autonomous vehicles through realistic simulations, we need behavior models that accurately estimate the (long) tails of human driver action distributions, that surround autonomous vehicles. In our preprint (under review), we investigate two approaches that focus on tail quantile estimation, including a version of normalizing flows, for this problem.

Bio

Short bio:

• Currently, I am a research scientist at the Bosch Center for Artificial Intelligence (BCAI).
• From 2017 to 2018, I was a postdoctoral researcher at the Empirical Inference Department of the Max Planck Institute for Intelligent Systems, Tübingen, Germany, working with Bernhard Schölkopf.
  • There I lead the research project "Cafeteria Coordination": machine learning and game theory for coordinating users of shared facilities and more efficient use of resources, based on a data privacy agreement reached with work councils.
• From 2013 to 2017 I pursued my PhD (Dr. rer. nat.) under the supervision of Dominik Janzing, Bernhard Schölkopf and Marc Toussaint at the Max Planck Institute for Intelligent Systems and the University of Stuttgart, Germany.
• In 2015, I did an internship at Microsoft Research Cambridge, United Kingdom, supervised by Katja Hofmann.
• From 2006 till 2012, I studied mathematics and philosophy at Humboldt University of Berlin and at Heidelberg University, Germany.
