Brian Karrer

Data Scientist - Core Data Science

I’m a research scientist on the Data Science team at Facebook. I received a PhD in physics from University of Michigan and a BA in mathematics and physics from Kenyon College. My current research involves building causal models of user behavior, applying distributed optimization to improve infrastructure systems, and developing experimentation methods for networked environments.

Interests

Statistical physics, complex networks, mathematical epidemiology, causal inference, and experimental design
