Norman M. Leff Assistant Professor of Physics and Assistant Professor of Physics
About
Professor Jo's research interest is studying exotic physics via novel materials. As each material system is like a small universe full of its unique mysteries, we gain new insights by discovering, understanding, and manipulating new materials. In the process, nature always gives us more challenges and shows us a new direction to study. Her current research focus is on correlated topological materials to address how interactions between quantum particles affect the topological phase of materials.
Professor Jo's primary experimental tools to unveil the mysteries of each material system are the following: solution growth method (flux method), X-ray diffraction, electrical transport, angle-resolved photoemission spectroscopy, and in-situ uniaxial stress tuning.
Professor Jo believes in the strong potential of collaboration/team science to understand intrinsic physics in the material comprehensively. She currently carries out part of her research at national laboratories, including Lawrence Berkeley National Laboratory and Ames National Laboratory. If you are interested in our research, please don't hesitate to get in touch.
For her work, Professor Jo is a recipient of the 2024 NSF CAREER Award, 2023 Outstanding Young Researcher Award.
