Research
My broad research interests include topics in geometric analysis, differential geometry, PDE, low dimensional topology, and graph theory. For specific information about details of and motivation for my work, please see the following research overview. Thank you for your interest!
A research colloquium talk I gave to a general mathematics audience at California State University-San Bernardino.
