Dr. Yagnaseni Roy is an Assistant Professor in the Centre for Sustainable Technologies (CST) at the Indian Institute of Science (IISc), Bangalore. Prior to joining IISc, she completed her post-doctoral training at the University of Twente, in the Sustainable Process Technology (SPT) group. She attained her MS and PhD degrees at the Massachusetts Institute of Technology (MIT), in Prof. John H. Lienhard's group in the Mechanical Engineering Department. Her postdoctoral and graduate work focused on inter-species selectivity in nanofiltration (NF) and reverse osmosis (RO) membranes, using both experimental and numerical modeling-based investigations. Her passion is in solving industrially and societally relevant separation problems by developing the techno-economically optimized ‘recipe’ using membrane separations and/or other separation technologies.
