Curriculum Vitae

Research Interests

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 of the page. See my Research Statement for a complete description of research interests.
