Assoc Prof Sunil C. Joshi

Biography
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 Mechanical Aerospace Engineering since 2000, presently part of Aerospace Engineering cluster. His expertise lies in the domain of Material and Structures and his teaching includes courses such as, Advanced Materials Engineering, and Structures and Materials. He was a member of XSAT, Singapore's first in-house designed and developed micro-satellite, team, where served as the team leader for the thermal controls sub-system.He was twice the chairperson of the AE accreditation committee that worked towards the accreditation of the BEng (AE) programme. He also served an area editor for an Elsevier Journal and often gets invited as reviewer for a number of premier journals.
