My research focuses on the design and analysis of efficient algorithms for learning, optimization, and inference problems, with a recent emphasis on their applications to data mining and business analytics. My works were built around the three basic pillars of theory: global optimization, dynamical systems, and statistical learning. During the period of years from 1999 to 2004, I started to work on global optimization algorithms and stability analysis for nonlinear control and power systems. My research progress has best been made by means of strong links between optimality and equilibrium, for example, by applying dynamical system approach to solve optimization or learning problems or by utilizing optimization or topology theory to analyze nonlinear dynamical systems. After a year of 2005, I have broadened this set of theoretical and computational tools to design new statistical learning algorithms (mostly kernel-based algorithms such as support vector machines and Gaussian processes), and to develop novel model calibration, pricing, and prediction techniques for financial derivatives. Recently I’m applying those developed techniques to solve real-world problems in data mining and business analytics. My research works can be classified into four areas; statistical learning, computational finance, global optimization & stability analysis, and data mining and business analytics, which is briefly described below.

In truth, it is not knowledge, but learning, not possessing, but production, not being there, but traveling there, which provides the greatest pleasure. When I have completely understood something, then I turn away and move on into the dark; indeed, so curious is the insatiable man, that when he has completed one house, rather than living in it peacefully, he starts to build another.
