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 Volatile Organic Compounds (VOCs) from gaseous and liquid waste streams.
  • Membranes for bio-separations.
