After 25 years as an applied mathematician in industry, the last 15 years spent in quantitative finance as a managing director with a well known hedge fund, I retired in 2004 and embarked on an academic career. My focus is on risk management, modeling the process of managing complex and dynamic portfolios, particularly those that naturally arise in so-called alternative investment strategies. This interest has found its expression in two areas of research: characterizing those interactions via regime-switching models and developing policies for risk control and capital structure management through micro-simulations.
