Bio: Jihyun completed her PhD (2019-2024) in Physics at Ewha Womans University, focusing on halide-perovskite interface engineering for high-efficiency, stable optoelectronic devices (Advisor: Prof. William Jo). From 2024 to 2025, she was a Postdoctoral Researcher in Prof. William Jo's lab, where she developed p-i-n-structured wide-bandgap perovskite solar cells. She has now started her postdoctoral position in the Hoye Group, co-supervised by Prof. Matthew Fuchter, working on 2D chiral perovskites and spin-selective optoelectronics. Her Oxford research was supported by the National Research Foundation of Korea's Postdoctoral Overseas Training Fellowship in her first year. This is followed by support from the group's NSF-ESRPC project, followed by funding from St. John's College through the large grant scheme.

Location: Inorganic Chemistry Laboratory, University of Oxford, Oxford
