Background 

Prior to joining UMD, Dr. Zhang was a Research Engineer in the School of Chemical and Biomolecular Engineering at the Georgia Institute of Technology, where he also obtained his doctoral degree in Chemical Engineering.

The overarching goal of his research is to reduce the CO2 footprints of large-scale separations, which currently consume roughly half of U.S. industrial energy use. Dr. Zhang’s lab aims to achieve this goal through leveraging material chemistry, transport, and scalable device fabrication to create advanced membranes for sustainable separation processes. More specifically, his research focuses on (1) understanding the control of molecular-scale membrane chemistry and structure to provide tunable transport properties for target fluid separations; (2) translating molecular-scale discoveries to hollow fibers with ultra-thin separation layers suitable for large-scale applications. His research addresses a broad range of challenging separation problems crucial to sustainable production of energy, clean water, bulk chemicals, and pharmaceuticals. Current interests include: (1) Membrane separation of hydrocarbon vapor mixtures; (2) Organic solvent nanofiltration membranes with tunable solvent permeability and ultra-high solute rejections; (3) Non-polymeric desalination membranes with ultra-high rejections of monovalent ions and low-molecular-weight uncharged solutes.
