Research interests

My current research interest is on Matrix Optimization with applications in finance and statistics. Prime examples include the (low-rank) nearest correlation matrix problem from finance; convex quadratic semidefinite programming in multidimensional scaling and optimal design of experiments; and shape-preserving curve fitting in regression models.

My past research interests include numerical methods for complementarity problems and variational inequalities; and stability analysis of delayed neural networks.
