Research Interests

My primary research interests are in theory, algorithms, and applications of nonconvex optimization. On the theoretical side, I work mainly on convexification techniques for mixed-integer and nonlinear (polynomial optimization) problems. I also have secondary research interests in computational discrete mathematics, particularly the structural study of convex polytopes and structural graph theory, and the use of tools from computational algebraic geometry in polynomial optimization. The theoretical results of my research have direct impact on accelerating convergence of global optimization algorithms for nonconvex problems. The motivating applications for my research come from various disciplines, such as chemical engineering, resilient network design, quantitative finance, game theory.

My research is currently supported by some EPSRC Impact Acceleration Awards for collaborative work with Police Scotland and Applied Quantum Computing, and a Edinburgh-Rice Strategic Collaboration Award 2022. In the past it has been funded by multiple grants from US federal agencies: National Science Foundation -- Computational Maths 2019-21 (sole PI) and NRT 2016-21 (co-Inv.), Office of Naval Research Mathematical Optimization 2016-20 (co-PI), Dept. Education GAANN 2015-18 (co-PI).

Biographical Statement

I am originally from Bombay (Mumbai), India, and after completing my Bachelor's degree, I moved to the USA for higher education. My Ph.D. degree is in Operations Research, with a minor in Mathematics, from Georgia Tech in Atlanta, Georgia. I worked as an Assistant Professor of Mathematical Sciences at Clemson University in USA where I got tenured and promoted to Associate Professor before moving to The University of Edinburgh in January 2020.
