Dr Gabseok Seo received PhD degree in Department of Energy Science from Sungkyunkwan University, South Korea in 2017 and worked as a Research fellow at Kyushu University and at International Institute Carbon-Neutral Energy Research (I2CNER) (2017-2019). During his Ph.D., he conducted a joint research with Distinguished professor Sang-Il Seok (UNIST, S. Korea) and professor Mohammad Khaja Nazeeruddin (EPFL, Switzerland). Currently, he joined the group of Professor Ji-Seon Kim as a Research Associate in Physics at the Imperial College London. His research focus is correlation between defect and charge generation and recombination mechanisms in Solution processed Inorganic-organic hybrid solar cells (Perovskite and Quantum dot).
