About Me

A photograph of a handsome bespectacled man with a mischievous smile

I am Cyrus Cousins, a recent Ph.D. graduate of Brown University in the BIGDATA group, under the tutelage of the great Eli Upfal. Before coming to Brown, I received my undergraduate degree in computer science, mathematics, and biology from Tufts University. My research interests lie primarily in showing novel techniques to bound uniform convergence rates and generalization error in exotic settings, and applying these bounds to tasks of real-world interest, most notably in data science, empirical game theory, and fair machine learning.

My favorite theorem is the Dvoretzky-Kiefer-Wolfowitz inequality, and my favorite algorithm is simulated annealing.
