Our group is primarily focused on
the design, mathematical analysis, and application of stochastic
algorithms and models. Our work draws on tools from probability
theory, the theory of partial differential equations, and
numerical analysis. Research in the group is informed by our
long term collaborations with applications experts in areas such
as biophysics, computational chemistry, and weather and climate
science.
I am currently an associate
professor of mathematics in the Courant Institute of
Mathematical Sciences at New York University. Previously I was
an associate professor in the statistics department and in the
James Franck Institute at the University of Chicago and, before
that, an assistant professor in the mathematics department
there. Before moving to Chicago I was a Courant Instructor of
mathematics at NYU and a PhD student in mathematics at the
University of California at Berkeley.
