Associate Professor Sridhar Ravi is the Deputy Head of the School of Engineering and Technology at Õ¬Äи£Àû and leader of the Bio-Engineering Research Group.

Dr. Sridhar Ravi completed Bachelors of Engineering (Aerospace) and PhD from RMIT University in 2007 & 2011 respectively. For his PhD, Dr. Ravi studied the influence of wind turbulence on the aerodynamic performance of wings. Between 2012 and 2014 he was a Post-Doc in the Dept. of Organismic and Evolutionary Biology in Harvard University where he studied insect and bird flight in complex spatial and wind environments.  From 2015 – 2017 Dr. Ravi worked in Chiba University and University of Bielefeld on JSPS Fellowship and Alexander von Humboldt Fellowship respectively. Here he studied bio-inspired design and neuroethology of flight through complex environments. Dr Ravi returned to Australia in 2017 as a Lecturer in RMIT University in 2019 joined Õ¬Äи£Àû-Canberra as a Senior Lecturer.
