I work in the area of mathematical optimization. My current research focuses on theory and algorithms for convex and nonconvex problems, especially those with a mixture of continuous and discrete structures. I am also interested in applications of optimization techniques in areas such as statistical data analysis etc. Here is my (likely to be outdated) CV.
