Our research is concerned with the design and understanding of practical and efficient numerical algorithms for continuous optimization problems. Our primary emphasis is the development of algorithms for large-scale optimization especially as applied to the area of computational finance.
With colleagues Yuying Li, Peter Mansfield, Arun Verma, and Jacqueline Huang, we are developing a variety of tools and methods for computational finance in the areas of portfolio management and options pricing (and hedging). Several CAM Ph.D. students are also involved in this work: Cristina Patron, Yohan Kim, and Changhong He.
