Large, interacting stochastic systems appear in many facets of
today's world and are of broad importance. Examples include the banking
system, financial markets, electric power grids, engineering systems,
health care, and social networks. Due to their scale, complexity, and
large amounts of data, analyzing such systems is inherently challenging
and will require new theoretical and computational approaches. My
research develops models, computational methods, and statistical tools
for such systems. I am particularly interested in developing new data-driven
approaches for modeling and optimization of these systems. My research has won the 2014 SIAM Financial
Mathematics and Engineering Conference Paper Prize. For a full list of papers and presentations, please see my CV at the top

description of research interests.
