Alistair Greig was trained as a Marine Engineer by the Royal Corps of Naval Constructors MOD(N) and spent time at sea on warships and submarines. His BSc(Eng) in Mechanical Engineering and MSc in Marine Engineering were completed at UCL. He subsequently studied for a part time PhD at UCL in underwater robotic applications. He was appointed as a UCL Lecturer in 1989, Senior Lecturer in 2001 and in 2016 Professor of Marine Engineering. He has a keen interest in Engineering Education and is the past Chair of WEGEMT's executive committee. He is a Chartered Engineering and FIMarEST and FIMechE.

Alistair Greig's research interests cover a broad range of topics including warship design, control and marine machinery integration with particular emphasis on advanced craft and the impact of new technology and legislation. Areas of interest include modelling marine propulsion plant and high speed multihull craft, in conjunction with partners in the USA under the ONR funded ACCESS project. Subjects encompassing the environmental impact of ships; ballast water exchange modelling (with Prof Eames); the Energy Efficiency Design Index (EEDI); low carbon shipping (with Prof Bucknall) and more efficient use of energy within ships.
