I completed my B.Tech. in Chemical Engineering from IT-BHU in 1991. I completed my MTech in Energy Studies from IIT Delhi in 1993. After submitting my Ph.D. thesis at Chemical Engineering IT-BHU in June 1996 I joined Lecturer Chemical Engineering at Shri Vile Parle Kelavani Mandal’s D.J. Sanghvi College of Engineering, Vile Parle Mumbai and thereafter joined Lecturer in Chemical Engineering IT-BHU in 1997. I wrote two books published by PHI Learning in 2009 (chemical engineering thermodynamics) and 2010 (introduction to numerical methods in chemical engineering) respectively and I got promoted to professor in Chemical Engineering IT-BHU in 2010. Thereafter I continued to work on the applications of numerical methods in fixed bed catalytic reactor (solving problems involving multiple reactions of diffusion and reaction in catalytic pellets) and multicomponent distillation (bubble point method, theta method, Naphtali Sandholm method with vapour liquid equilibrium involving modified Raoult’s law, activity coefficients calculated using Wilson model) and wrote second edition of introduction to numerical methods in chemical engineering book published by PHI Learning in 2019. Presently also I continue to work on solving computer-oriented problems in chemical engineering using numerical methods.
