Overview
Our research focuses on understanding and controlling molecular and ionic transport in advanced materials for sustainable separations. We investigate how nanoscale structure, chemical functionality, and molecular interactions govern material properties and performance. Combining materials design, synthesis, and characterization with transport studies, we seek to develop membranes that selectively separate closely related molecules and ions. Our work connects nanoscience, materials science, and chemical engineering to enable energy-efficient separations, resource recovery, and more sustainable industrial processes.
