Joined as a Lecturer in the Department of Chemical Engineering in the November 1988, then promoted to lecturer selection grade from November 1998, afterwards placed as Associate professor from January 1st 2006. During M Tech dissertation at IT BHU followed by Junior Research fellowship in the same institute. Major research area was catalyst development and characterisation. Now the research and guidance are carried out in the field of Heat Transfer, Thermosiphon Reboiler, Modelling and Simulation and soft computing. Paper in these area had been published in the best national and international Journal of Chemical Engineering discipline say Indian Chemical Engineer, Journal of Scientific and industrial Research, Institution of Engineers (Chemical Engineering Section), AIChE, Aplied Thermal Engineering and Chemical Engineering Research and Design. A wide range of subjects had been thought at under and post graduate level. A large number of projects had/has been guided at UG level in the above mentioned fields. Many M Tech dissertation in the area of modeling and simulation were/are supervised.
