My name is Lea Cohausz and I’m a PhD student specializing in Artificial Intelligence at the University of Mannheim. I am notoriously interested in many things which is reflected in pretty much every aspect of my life.

Research Interests

  • causal modelling and causal structure learning
  • causal modelling and fairness
  • Explainability
  • combining causal inference and predictive models
  • much of the above in the context of Educational Data Mining
  • (AI-Planning and Reinforcement Learning for Goal and Plan Recognition)

If you are interested in any of these topics, feel free to reach out to me.

Education

  • since 2021: PhD student at the University of Mannheim (Computer Science)
  • 2018-2020: M.Sc. Data Science, University of Mannheim
  • 2018-2021: M.A. Sociology, University of Mannheim

Scholarships

  • 2017-2021: Studienstiftung des deutschen Volkes (German Academic Scholarship Foundation)
  • 2016-2017: Deutschlandstipendium

Teaching

I am actively involved in teaching several courses:

  • Decision Support: Master-level course on the basics of logic and probability theory, graphical models (in particular BNs), utility theory, game theory, and reinforcement learning
  • Industrial Applications of AI (my sessions: agriculture/computer vision and education/XAI/causal modelling and biases): hands-on Master-level course
  • Master Team Project and Master Seminar Content Recommendation

Workshops & Tutorials

I have (co-)organized workshops and tutorials:

  • EDM 2024: Tutorial on Thinking Causally in EDM: A Hands-On Tutorial for Causal Modeling Using DAGs
  • EDM 2024: Workshop on Human-Centric eXplainable AI in Education (HEXED) with Juan D. Pinto, Luc Paquette, Vinitra Swamy, Tanja Käser, and Qianhui Liu
  • DELFI 2024: Workshop on Learning Analytics: Study Path and Curriculum Analytics with Frederik Baucks and Niels Seidel

Interests Outside Academia

I enjoy being outside, going on hikes, bouldering, sailing, playing all kinds of sports, and being a volunteer firefighter.
