Ji-Seon Kim

Professor Ji-Seon Kim (Oxford) serves as Professor of Electronic Materials in the Department of Chemistry, joining Oxford in 2025 under the Sustainable Chemistry & Materials Initiative. Her research centers on sustainable molecular semiconductors, expanding to include mixed electronic/ionic conductors and organic/inorganic hybrid materials. She explores how molecular structure, interfaces, energetics, and dynamics influence device performance in applications such as solar cells, photoconversion sensors, synaptic transistors, biosensors and displays. Her methods combine advanced nanometrology (vibrational spectroscopy, Kelvin probe, photoemission) with density functional theory modeling to reveal the molecular origins of device behaviour. Recognition of her contributions includes the 2023 Nevill Mott Medal for her integrative approach to the materials physics of molecular semiconductor devices.
