Dr. Guanhe Rim received B.S. and M.S. in Chemical Engineering at Sungkyunkwan University, South Korea, and a Ph.D. in Earth and Environmental Engineering at Columbia University in 2020 under the guidance of Prof. Ah-Hyung Alissa Park. His Ph.D. research focused on coupled kinetic and mechanistic studies of elemental extraction from silicate minerals and alkaline industrial wastes for CO2 utilization, and he designed a unique internal grinding reactor system to enhance diffusion-limited elemental extraction behavior. Currently, Dr. Rim is continuing his research in Prof. Christopher W. Jones’s and Prof. Ryan P. Lively’s groups at the Georgia Institute of Technology as a postdoctoral Fellow. His research focuses on the synthesis and characterization of amine-impregnated MOF powder/monolith sorbents for sub-ambient DAC (direct air capture).
