Dr. Cho joined the Department of Physics at Hope College in fall 2022. Before coming to Hope, he worked at Ames Laboratory for 11 years to conduct low-temperature research in unconventional superconductors such as Fe-based and Copper-Oxide superconductors. His current research is focused on revealing the energy gap of unconventional superconductors. In particular, he is very interested in using the local particle accelerator located at the campus of Hope College to study the effect of high energy particles on the superconducting energy gap. Dr. Cho is a member of the American Physical Society (Division of Condensed Matter Physics).
