He graduated in Mechanical Engineering in 1999 from Jadavpur University, Calcutta with First Class Honours and with a University First Rank (Gold medal) in Bachelor of Mechanical Engineering. In the same year he obtained an All India First Rank in the Graduate Aptitude Test in Engineering Examination (GATE). He did his Masters degree (ME) in Mechanical Engineering with a specialisation in Computational Heat and Fluid Flow from the Indian Institute of Science (IISc.), Bangalore, with a University First Rank (Gold medal with senate commendation). In this Masters project he worked on the RANS modelling of turbulent transport in weld-pool convection. He gained industrial experience as a Mechanical Engineer in General Electric (GE), India before getting the prestigious Gates Cambridge Scholarship for pursuing a PhD at Cambridge University. In Cambridge. The title of his doctoral thesis is 'Fundamental Study of Turbulent Premixed Combustion using Direct Numerical Simulation'.
