Turning real-world data into better operating decisions. I use operational data, field experiments, and causal inference to understand what works—and to identify actionable improvements in healthcare and pharmaceutical supply chains, retail and services, platforms, and AI-enabled work.

Research Areas
Research grounded in real operating problems
Healthcare & Pharmaceutical Supply Chains
Disruption recovery, resilience, capacity design, drug shortages, operational transparency, and equitable access.
Retail & Service Operations
Store labor, incentives, customer congestion, fitting-room traffic, product variety, and service productivity.
Platforms & Digital Operations
E-commerce fulfillment, platform-provided logistics, technology-enabled services, kiosks, and digital customer responses.
Empirical OM & Causal Inference
Field experiments, difference-in-differences, instrumental variables, matching designs, and quasi-experimental methods.
Featured Research
Selected research and its operational implications
Management Science, Articles in Advance · 2026
Drug Shortage Recovery
Each additional shortage previously resolved by a plant reduces recovery time for a current shortage. Learning is concentrated in internally caused shortages, benefits from broader experience, and transfers only weakly across plants within the same firm.
Management Science, 67(4): 2326-2339 · 2021
Drug Shortage Transparency
Mandatory interruption reporting alleviates shortages, but its effectiveness depends on product-market competition: the effect is strongest under duopoly, weaker under monopoly, and declines as competition intensifies.
Manufacturing & Service Operations Management, 23(6): 1580-1596 · 2021
Fitting-Room Traffic
Fitting-room traffic and sales have an inverted-U relationship. High traffic increases phantom stockouts, and dedicated fitting-room associates reduce phantom stockouts and increase sales by approximately 22.4%-22.7%.
Research Group & Opportunities
Students working on consequential operations questions
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
Fitting-room product trials and sales
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
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
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
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.
Student Achievement · 2026
Saeyoung Yoon: Selected for 2026 NRF doctoral student research funding
The 24-month project uses RFID fitting-room try-on logs to study conversion to SKU-level sales and demand spillovers within the same apparel style.
