Research Interests

Fabrication of hollow fibers using newly synthesized and commercially available polymer for various membrane application is my key research interest. Bringing innovation within HF fabrication process (multi-bore fibers, corrugated fibers, etc.) and post modification (coating, plasma etching, etc.). Has been working for various application like Membrane distillation, Pervaporation, Membrane dehumidification, Membrane emulsification etc. using microporous, nano-porous and dense flat/HF membranes based on required separation process.
