“Beating COVID-19: How mathematics and game theory can help us understand the pandemic”

with Chris Bauch

Wednesday, March 3 at 4:00 pm and 7:00 pm ET (New York)

Mathematical modeling has come to the forefront during the COVID-19 pandemic, but how do these models work?  Join Dr. Chris Bauch, Professor of Applied Mathematics at the University of Waterloo, as he sketches the mathematics behind “flattening the curve” and herd immunity.  Learn why flattening the curve reveals an interplay between disease spread and population behavior and how members of the population can be viewed as engaging in a strategic interaction with one another — a “game” — that determines the trajectory of the epidemic.  Take part in an audience participatory example, illustrating how these interactions can be analyzed mathematically using game theory — and how math really can help us emerge victorious.

Special introduction by Julie Gerberding, former director of the CDC and current Executive Vice President and Chief Patient Officer at Merck.

This is a live-streamed event.  Occasional video recordings are made available for a fee at
