Benjamin Bloem-Reddy

I am Assistant Professor of Statistics at the University of British Columbia. I work on problems in statistics and machine learning, with an emphasis on probabilistic approaches. Some recent examples:

  • Uses and benefits of symmetry in statistics, computation, and machine learning.
  • Models and inference methods (SMC, MCMC) for evolving processes (e.g., networks, forest fires) whose history is partially or full unobserved.
I have a growing interest in causality and its interplay with knowledge and inference. I also collaborate with researchers in the sciences on statistical problems arising in their research.

I was a PhD student with Peter Orbanz at Columbia and a postdoc with Yee Whye Teh in the CSML group at the University of Oxford. Before moving to statistics and machine learning, I studied physics at Stanford University and Northwestern University.
