About

Welcome! My name is Joonho (pronounced like Juneau, the capital of Alaska).

I am an Assistant Professor in the Operations and Decision Technologies department at Indiana University’s Kelley School of Business.

My research develops mathematical models at the intersection of operations, marketing, and engineering. I am particularly interested in sustainable operations, energy markets, battery energy storage systems, risk management, and data-driven decision making.

I received my Ph.D. from the Stephen M. Ross School of Business at the University of Michigan. I also hold an M.S. from KAIST and a B.S. from Seoul National University. Before academia, I co-founded and led ChamSonGil Cooperative, a social venture supporting blind massage therapists, and worked at SK Telecom as a marketing manager.
