My research interests span: Risk Analytics and Robust Optimization, Data-Driven Decision-Making, Sequential Decision-Making, and Data Science/AI for Operations Management (especially applications in social good/sustainability). I entertain a strong interest for quantitative methodologies that can help manage the risk, uncertainty and ambiguity for engineering and service systems.
