Research Interests

My primary interest lies in statistical models for machine learning. My goal is to obtain a deeper understanding of currently available methods. I intend to create quality models that are generically applicable and easy to use. My research interests include in particular:

  • multivariate probability distributions (for example, latent variable graphical models)
  • convex optimization solvers (ADMM, proximal point methods)
  • causality
