B. R. Gupta received his Ph. D. from I I T Kharagpur in chemical Engineering in the field of "Rheology of rapidly settling suspensions". He worked as a faculty member at IIT Kharagpur for more than three decades initially in the Dept. of Chemical Engineering and then in Rubber Technology Centre. He has served as Emeritus Professor at (AICTE) at SJC College of Engineering, Mysore, Karnataka. Dr. Gupta's research areas are Polymer Rheology and Processing, Waste Rubber Recycling, Chemical Modification of Rubbers and Rheology of filled systems. He has guided a number of Ph.D. and masters degree students. He has published more than 80 research papers in reputed international journals and 3 books; one on Polymer rheology; another on Polymer processing Technology; and one on Rubber processing on a Two Roll Mill. Dr. Gupta retired in the year 2004.
