Summary
Debashis is from India and has a background in Mechanical Engineering. He obtained his bachelor’s degree from B.P.U.T. Odisha (2007-2011) and a Masters in Tribology and Maintenance Engineering from I.I.T. Delhi (2011- 2013). He joined the Tribology group at Imperial College for his PhD level studies under the supervision of Dr. Tom Reddyhoff.
His PhD Thesis titled ''Triboemission-Lubricant Interactions" elucidates various novel methods to observe emission of ions, electrons, photons from contact interface. Extensive studies on charging, material transfer and generation of plasma from various rubbing surfaces were carried out to ascertain the potential role of the triboemission in boundary film formation upon interaction with lubricants. During his PhD, he was awarded two poster awards and two travel grant awards.
His current project is on "Tribology of High-performance polymers". This project is aimed at a fundamental understanding of the formation of transfer films of High-performance polymers at Steel-Polymer interface and their subsequent effect on friction and wear properties in different environment and operating conditions.
