Publications and Research Philosophy

Published in flagship journals of INFORMS (e.g., Operations Research, Management Science, Math. of Oper. Research, and Transportation Science) as well as several papers in Mathematical Programming.   In addition to leading algorithmic advances in Stochastic Optimization, the research has been adopted in commercial software supporting solvers for stochastic optimization models. The research on Infrastructure Systems includes applications in power system operations, telecommunications network design and vehicular traffic control. These applications have not only implemented state-of-the-art methodologies, but have also motivated new algorithms for stochastic optimization. This symbiosis between new stochastic optimization algorithms and new applications makes this research rigorous and impactful.
