Assistant Professor of Computer Science
Field Member of Applied Math
Cornell University
My research develops numerical methods and computational frameworks
for analyzing and understanding largescale and complex datasets. I
often approach problems with some combination of network science,
matrix and tensor computations, and machine learning.
