Dr. Sunil C. Joshi obtained his M. Tech. degree in Aeronautical Engineering with aircraft structures specialization. He received his Ph.D. degree from Monash University (Australia) for his work on composites manufacturing processes. Prior to that he was a Scientist at National Aerospace laboratories, Bangalore, India, where he was part of the composite structures group from 1988 to 1994.
He has been an academic staff in the School of MAE since 2000 and presently he is under the division of Aerospace Engineering. He is also a member of the micro-satellite development team at NTU and is serving as the team leader for the thermal controls sub-system.
His research interest are detailed below. He has published over 60 international conference and journal papers. He is often invited as reviewer for a number of premier journals, including Composites Science and Technology, Int Jr of Mechanics and Materials in Design, Int Jr of Manufacturing Research, Jr of Applied Polymer Science, and Composite A – Applied Science and Manufacturing. Dr. Joshi is a member of the Society of Plastics Engineers, The International Plastics Society, USA. He has also served the Society for Theoretical and Applied Mechanics, Singapore, as the Secretary and Treasurer.
His research expertise encompass – Process modelling for composites, Transition mechanisms in hydrogels, Composite repairs, and Thermal controls for micro-satellites.
