Dr. Ramkumar received his B.E in Mechanical Engineering from College of Engineering, Guindy, Anna University and his M.Tech (Industrial Tribology) from IIT Madras. He obtained his Ph.D. (2003-07) from University of Southampton with specialisation of Engine Tribology, UK and did his post-doctoral fellowship in University of Leicester (2009-10), UK for developing high speed Cam-Tappet tribometer Rig. He has 14 years research experience in the field of tribology and engine tribology. He won the best presentation award for his PhD from IMechE, London, UK in 2005. His primary research interests are in the field of tribology, engine tribology, gearbox design, wind turbine gearbox bearing failures, biotribology, multilayer coatings, ionic fluids, wear modelling and developing new composite materials for brake applications. He has published more than 20 papers in peer-reviewed journals and 40 international conference proceedings including 1 patent as well. As sole PI, he has received two research grants with total worth of US $1.4M, while as Co-PI US $ 14M from DST. Currently, he is handling a lot of consultancy projects from GE, Caterpillar, Rane, Ford, Kone Elevator and L&T. In his supervision 3 MS scholars and 14 M. Tech. students were graduated and currently he is supervising 8 Ph.D., 5 MS research scholars, 2 project associates, 1 JRF and 2 M.Tech. degrees students. He is a member in IMechE, IoP, STLE, and life time member in TSI. He is reviewer to various top journals including Applied Surface Science, Mechanism and Machine Theory, Part J : Journal of Engineering Tribology, Surface Coatingsand Technology, Tribology International, Tribology Letters, Wear, etc.
