Dr. Seo received the Ph.D. degree in Electrical Engineering from Seoul National University, Seoul, South Korea, in 2015. From 2016 to 2017, he was a Research Associate with the Colorado Power Electronics Center, University of Colorado, Boulder, CO, USA. Since 2018, he has been with the Power Systems Engineering Center at the National Laboratory of the Rockies (formerly the National Renewable Energy Laboratory [NREL]), Golden, CO, USA, where he is currently a Principal Engineer and leads research projects focused on power electronics and power systems applications for power grids with high integrations of inverter-based resources. 

He has coauthored more than 100 journal and peer-reviewed conference papers. He received the First Place Prize Paper Award of the IEEE Transactions on Power Electronics in 2025. He has been listed in the World’s Top 2% Scientists by Stanford University and Elsevier since 2022. He coauthored the Research Roadmap on Grid-Forming Inverters (NREL 2020). 

His current research interests include power electronics for sustainable energy systems and microgrids and power systems engineering for grid modernization, including grid-forming inverter control, inverter-driven power system black start, and medium-voltage and high-voltage direct current power electronics for low- or zero-inertia grids to improve grid resilience and stability.
