Jihoon Moon

Battery systems researcher specializing in fault diagnostics, state estimation, and control.

About

I am a Research Fellow at the U.S. Food and Drug Administration’s Center for Devices and Radiological Health. I earned my Ph.D. in Mechanical Engineering from The Pennsylvania State University under the guidance of Prof. Christopher D. Rahn. My dissertation, "Fault diagnosis, mitigation, and long-term damage evolution in lithium-ion batteries," was defended in February 2026 and I graduated in August 2026.

My research sits at the intersection of control theory and energy systems, with a focus on electrochemical modeling, state estimation, and safety-critical, data-driven control of lithium-ion batteries. I have collaborated with the National Highway Traffic Safety Administration and Idaho National Laboratory.

Previously, I interned at Tesla on the Cell Lifetime Modeling team from August to December 2024.

Research Agenda

My future work will focus on integrating physics-based and data-driven modeling and control approaches for energy systems, while also advancing foundational research in control theory.
