My research focuses on: (1) designing efficient algorithms for matching supply with demand that achieve robust worst-case performance guarantees, and (2) managing operational, financial, and environmental risks in projects and supply chains.
My teaching interests include (are not limited to) operations management, supply chain management, optimization, and business analytics (predictive & prescriptive analytics).
