Seth Flaxman

Scalable spatiotemporal statistics and Bayesian machine learning for public policy and social science

Seth was a postdoc working on scalable methods for spatiotemporal statistics and Bayesian machine learning, applied to public policy / social science areas including crime and public health. He completed his PhD at Carnegie Mellon University in August 2015 in a program that is joint between public policy and machine learning.

Seth is now a lecturer in the statistics section of the Department of Mathematics at Imperial College London, joint with the Data Science Institute.
