I am currently an Assistant Professor at TIFR Bangalore. 

From 2015-2018, I was a Visiting Assistant Professor at Oklahoma State University. Prior to that, in 2014-2015, I was a postdoc working with Siva Athreya in the Stat-Math unit of ISI Bangalore

I graduated with a Ph. D in Mathematics from Purdue University in May 2014. My thesis advisors were Alexandre Eremenko and Svitlana Mayboroda.


My research interests are in Complex Analysis, Potential theory, and Probability. I have worked on various quantities associated with the Laplacian (e.g Martin kernels, harmonic measures, and exit times of Brownian motion), and general Euclidean potential theory. I am currently thinking about analytic problems with a probabilistic flavor.
