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 has been funded by multiple grants from US federal agencies - (1) National Science Foundation (NSF) Computational Mathematics grant 2019-21 (sole PI) (2) Office of Naval Research Mathematical Optimization grant 2016-20 (co-PI), (3) NSF NRT grant 2016-21 (co-Inv.), (4) Department of Education GAANN grant 2015-18 (co-PI).
