FACULTY
Biography
Neelkanth Nirmalkar earned his Ph.D. in Chemical Engineering from the Indian Institute of Technology Kanpur. Following a post-doctoral research experience in the Department of Chemical Engineering, The University of Birmingham, UK, he joined IIT Ropar in 2019 as an Assistant Professor in the Department of Chemical Engineering. His research interests include non-Newtonian fluid mechanics and heat transfer in multiphase flows. In recent years, he has been investigating complex fluids and flow, heat transfer in nanofluids, heat transfer in phase change materials and the stability of bulk nanobubbles with potential applications in mineral processing, and water treatment. He also works in the formulation of conductive inks, aerogels, ionic liquids, phase change materials, carbon nanofibers and nanotubes, fabrication of hydrophobic nanomembranes.
