About Me:
My research interests are generally in nonlinear partial differential equations. I am particularly interested in asymptotic problems from fluid mechanics.
I received my Sc.B. (2012), Sc. M. (2018), and Ph.D. (2013-2018) from Brown University, where my advisor was Yan Guo. I was an NSF postdoc at Princeton University from 2018-2021. Since July 2021 I have been an Assistant Professor at UC Davis.
Here are some aspects of my online footprint:
