Research Interests
My research interests lie in the mathematical and statistical modeling of large, complex systems, with one
of my primary focuses being financial systems. Due to their scale and complexity, analyzing such systems
is inherently challenging. I am particularly interested in developing datadriven models that take advantage of the large amounts of
data typically available for such systems. To address problems in this area, I employ tools
from stochastics, partial differential equations, optimization, statistics, and machine learning. My dissertation papers address several
key challenges arising in this area. For a full list of papers and presentations, please see my CV at the top of the page.
