He was the CEO & Director of the Singapore–MIT Alliance for Research and Technology (the "SMART" Centre), and prior to that the Head of the Department of Mechanical Engineering at MIT.
Born to L.B. "Malcolm" Abeyaratne, CCS former Secretary to the Treasury and Enid Abeyaratne, he was educated at the prestigious Royal College Colombo where he won the Turnour Prize in 1967 and was Head Prefect in 1970.
