My current research focuses on Operations Management under Financial Frictions. More specifically, I study how financial frictions affect operations decisions and strategic interactions between different parties in supply chains. Topics that my research covers include: trade credit (including reverse factoring, trade credit insurance), supply chain interactions under bankruptcy, and operational improvements via innovative financing (e.g., purchase order financing).
