Academic Profile

Prof Joshi has been a faculty at the School of Mechanical & Aerospace Engineering since Nov 2000. He was awarded PhD for his work on Composites Manufacturing Processes, by Monash University, Australia in 1999. Prior to that, from 1988 to 1994, he worked as a Scientist at the National Aerospace Laboratories, Bangalore, India, upon completion of his M.Tech. in Aeronautical Engineering from Indian Institute of Bombay (Mumbai). At NTU, Prof Joshi was an integral part of the Singapore’s first microsatellite R&D project, XSAT, which was successfully launched in 2011. He has been PI or co-PI of several R&D projects funded by ASTAR, RSAF, DSTA, as well as, industries, such as ARKEMA and LH. Currently, he has more than 200 research publications (journals, conferences, books, patent) to his credit.

Prof Sunil has worked on several R & D projects funded by external agencies and industries. He was the team leader responsible for designing and developing thermal controls for XSAT, Singapore's first fully designed and built micro-satellite. XSAT was launched successfully in 2011, and has since completed its intended mission. Dr. Sunil has been holding concurrent School Management positions. He was the Assistant Chair (Graduate Studies) from 2014 to 2017, and, the Associate Chair (Academic) from 2017 to 2020. He had chaired the School Accreditation Committee twice, in 2011 and 2016, which worked towards preparing for the full accreditation of the B.Eng. (Aerospace Eng) programme under the Washington Accord.
