Research:
My research is broadly in applied mathematics with current
research interests at the intersection of matrix completion,
compressive sensing, highdimensional probability and convex
optimization. In the theoretical side, my work has used tools from
probability to assess the effectiveness of certain convex
optimization algorithms. The problems I study originate from
consideration of real world applications. As such, they motivate the
construction of a mathematical model and the design of algorithms
that could handle noisy/incomplete data. A common thread in my
research is a theoretical analysis of convex approximations and a
principled design of algorithms for possibly large scale problems.
Some of my research topics are:
 Algorithms for the distance geometry problem
with the goal of determining 3D protein structure
 Fast convex algorithms for the graph matching
problem
 Theoretical analysis of deep learning in certain
applications.
