He received the B.E.(hons 1) degree in interdisciplinary systems engineering in 1994 and the Ph.D. degree in Telecommunications Engineering in 1999 from ANU. From 1995 to 1997, he worked as a Research Engineer at the Arthur C. Clarke Centre for Modern Technologies, in Sri Lanka. Since December 1999, he has been a faculty member at ANU.
Thushara considers 'research training' as a top priority. He has supervised about 30 PhD students and 6 Mphil students. He rarely writes alone and has co-authored over 230 peer reviewed papers.
He is an associate editor for IEEE Transactions on Audio, Speech and Language Processing and EURASIP Journal on Wireless Communications and Networking and was a member of the Audio & Acoustics Signal Processing Technical committee of the IEEE Signal processing Society (2011-16).
Physically inspired signal processing problems in the areas of Acoustics and Spatial Audio; Wireless and Mobile Communications; and Bio-medical applications. These include spatial sound-field recording and reconstruction, broadband/ nearfield beamforming, array signal processing, photo-acoustics, wireless channel modelling, capacity analysis of spatial channels, wave propagation modelling, and MIMO systems.
