Joseph Lai is Emeritus Professor in the School of Engineering and Information Technology (SEIT). He was the Associate Dean (International) at UNSW Canberra,ADFA from May 2012 to Dec 2016. Prior to this appointment, he was the Associate Dean (Research) from 2004 to April, 2012 and Professor in Mechanical Engineering in SEIT. He was elected Fellow of the Institution of Engineers Australia in 1993. He is a Fellow of the Australian Acoustical Society and an Associate Fellow of the American Institute of Aeronautics and Astronautics.  Professor Lai’s research interests are in turbulent shear flows and acoustics and vibration control, with over $3m external research funding in the last 10 years.  His current work is focussed on the aerodynamic propulsive mechanism of flapping wings as applied to micro-aerial vehicles and high altitude long endurance vehicles and wind/wave power generation, and vibro-acoustic communication in termites.
