**Research**

My main interests are in stochastic analysis, in particular stochastic differential equations. I also have interests in applied mathematics, and some of my research
in this area has been featured in popular press: DukeToday,
Pharmacy Times,
Futurity,
WUNC,
Healio,
ACSH, ICT, AHC Media. Currently, my research is supported in part by grants DMS-1612898 and DMS-1855504 from the National Science Foundation.
