Nitish's core research focus is on developing lower-order fouling models that connect mechanistic membrane fouling science with large-scale water treatment planning. His work integrates experimental, pilot-scale, and operational data with technoeconomic and decision-support modeling to guide sustainable water and energy system design. He earned his Ph.D. from the University of Toronto in Canada, following an M.Sc. from the University of Alberta and a B.Sc. from the Bangladesh University of Engineering and Technology. His research spans solar desalination, separation processes design and characterizations, and decentralized water treatment and sanitation.
