Hello There! I'm an ELLIS PhD student advised by Steffen Staab (ELLIS, University of Stuttgart) and Antonio Vergari (University of Edinburgh). I'm generally interested in making ML systems learn better from data with inherent symmetries and where the i.i.d. assumption does not hold. Here are some of my (very) wide sets of interests,

  • Contrastive learning
  • Probabilistic Knowledge Graphs
  • Equivariant GNNs
  • Rethinking Evaluations for ML systems
  • ML systems with inspirations from Evolutionary Biology

Feel free to reach out to me through my email if you want to have a chat about ideas!
