Research interests

My research concerns duality theory, and the construction and complexity of algorithms for mathematical optimization problems. Using large-deviations techniques, I'm also applying convex analysis and convex optimization theory to the analysis of optimal alignments of random sequences. My modelling work concerns applications of conic optimization to solve financial problems, particularly in asset management and in risk management.
