With a background in energy and medical device research, Hanseo Kim specializes in nanomaterials, supercapacitors, and their interdisciplinary applications across sustainability and biomedical engineering. Currently a Materials Science & Engineering student at Northwestern University, Hanseo has conducted award-winning research at Kyungpook National University, where he developed a moisture-powered thin-film supercapacitor for carbon capture and a hydrogel patch capable of detecting muscle activity and fatigue.


Hanseo’s work has earned him national and international acclaim, including the Korea Minister of Trade, Industry, and Energy Award, 1st Place in Engineering at the 2025 Taiwan International Science Fair, and recognition as one of South Korea’s top high school researchers at the 2023 Korea Science & Engineering Fair. His supercapacitor project was selected as one of only three to represent Korea at the 2024 European Union Contest for Young Scientists (EUCYS), where he received the ISTF Prize.


A 2025 admit to Northwestern University, Hanseo was also accepted to top colleges such as the University of Chicago, UCLA, University of Michigan, GeorgiaTech, and etc.
