I am an RTG Postdoctoral Fellow at Northwestern University. My research is partly supported by NSF Grant DMS-1901427 "Stability of functional and geometric inequalities and applications'' (2019-2022).
I was a member of the Institute for Advanced Study for the 2018-19 academic year, participating in the special year on Variational Methods in Geometry there.
I completed my Ph.D. at UT
Austin under the supervision of Alessio Figalli
Maggi. I work in the calculus of variations, PDE, and geometric analysis.
You can find my CV here (last updated March 2021).
