Dr. Bidhan Chandra Sardar is an Assistant Professor in the Department of Mathematics at IIT Madras. He obtained his Ph.D. (2012–2016) and M.S. (2010–2012) from IISc Bangalore, following his B.Sc. from the University of Burdwan (2006–2009). Before joining IIT Madras, he served as an Assistant Professor at IIT Ropar (2019–2024) and is currently on lien from IIT Ropar. He also held postdoctoral positions at IIT Kanpur (2017–2019) and TIFR-CAM, Bangalore (2016–2017). His research interests lie in the areas of partial differential equations, homogenization, and optimal control theory.
