Research Group
Students, research, and opportunities
Research mentoring emphasizes empirical operations and supply chain management, careful causal identification, institutional knowledge of operational settings, and student-led projects that connect rigorous methods with consequential operations problems.
Current student projects examine retail technology, healthcare delivery, and supply-chain resilience using operational data, field knowledge, and empirical methods.

Retail Operations
Saeyoung Yoon 윤세영
Current research
Fitting-room product trials and sales
“Try Before You Buy: How Fitting Room Usage Influences Apparel Sales and Spillover Effects”
Uses RFID fitting-room try-on logs and SKU-level sales data to examine how product trials translate into purchases and demand spillovers across variants of the same style.
Healthcare Operations
Sang Yong Park 박상용
Current research
Operating-room scheduling
Uses a decade of operating-room records from a South Korean tertiary hospital to examine how schedule deviations change pacing during anesthesia and surgery and relate to reoperations and postoperative complications.
Supply Chain Management & Resilience
Jongcheol Won 원종철
Current research
Supply-base de-scaling and resilience
Uses Korean VAT-based firm-to-firm transaction and financial data to examine how persistent pre-COVID supplier-base de-scaling relates to firms’ inventory responses and financial outcomes during the pandemic.
Healthcare Operations
Claire Shin 신재아
Current research
Physician learning in emergency departments
Uses Hong Kong emergency-department visit data to examine whether physicians reduce service times as experience accumulates and how learning transfers across patient triage levels.
