Research

Please find my research statement.

My research mission is to develop rigorous methodologies to solve a class of problems which I define as Responsible Operations, Analytics, and Design (ROAD). Here, Responsible has a two-pronged meaning. First, these methodologies are developed responsibly, i.e., in an interpretable and trustworthy way. Second, I apply these methodologies to my responsible vision, i.e., toward (1) resilient, (2) circular, and (3) humane supply chain network and economy (SCNE). Currently, these methodologies lie at the intersection of stochastic and contextual optimization, causal inference / empirical methods, and algorithmic/continuous approximation techniques. I am passionate about pursuing this research mission because not only are these problems important to society but also because I believe there is a tremendous opportunity to solve these important problems by developing novel models and methods that are interesting and impactful.
