Research Interests

My research interests are primarily in the area of membrane science and technology, including membrane formation and characterization, transport studies, module design, and process development. The following projects are currently being carried out, and some of them are undertaken in collaboration with our research partners:

Development of hollow fiber membranes and membrane modules
Synthesis, modification and characterization of asymmetric/composite membranes
Nano-structured membranes for olefin/paraffin separations
Pervaporation, gas separation, and membrane distillation
Membrane reactors
Membrane-modulated absorbers,adsorbers, and spargers
Synergetic integration of membranes with traditional separation processes
CO2 separation for greenhouse gas emission control
Separation of VOCs from gaseous and liquid waste streams
Membranes for bio-separations
