Dr. Jin Hyun Chang joined the Department of Energy Conversion and Storage at the Technical University of Denmark (DTU) as a postdoc in 2016, and he became an assistant professor in 2019. His main research focus is on (1) understanding the physicochemical properties of battery materials using atomistic simulations such as density functional theory (DFT) and (2) developing computational methods to use DFT simulation results on larger scales using artificial intelligence. During his PhD at the University of Toronto (Canada), he investigated the electronic structures at the electrode-electrolyte interfaces for supercapacitor applications, and he worked in industry as a research scientist in the field of water treatment technology. His current research interest is on developing new materials for both Li-ion and post-Li-ion batteries.
