From August 2008 to August 2014, I was a Ph.D. student in the School of ORIE, advised by James Renegar.

I am currently an Assistant Clinical Professor in the Department of Mathematics at New York University.

My primary research interests are in mathematical programming and continuous optimization. My dissertation work focuses on the analysis of a novel interior-point algorithm for linear and semidefinite programming.

More broadly, I am interested in applying optimization and computational methods to problems that arise from real applications and from other disciplines.
