Passive Acoustics • Automatic Pattern Recognition • Statistical Learning • Signal Processing
My current research involves developing solutions for automatic source separation in continuous ambient audio streams and the development of acoustic deep-learning techniques for unsupervised multi-class classification in the big-data realm, with focus on efficient utilization of modern computing capabilities in achieving real-time performance.
My research interests have been largely multidisciplinary. In the past, I worked as a speech scientist for a leading Automatic Speech Recognition (ASR) solutions provider, before steering my career into bioacoustics and allied disciplines. My Masters thesis offered passive acoustic solutions to monitoring free-ranging blue and fin whales in the Pacific Ocean, and my doctoral research involved development of solutions for the automation of underwater soundscape assessments.
Prior to joining Cornell, I was a research associate with the Centre for Marine Science and Technology (CMST) in Australia, a research associate at the National Institute of Oceanography (NIO) in India , and a postdoctoral research fellow at the Indian Institute of Science Education and Research (IISER-Tirupati), also in India.
I have been actively involved with IEEE’s Oceanic Engineering Society (OES) as an AdCom member and, currently, I serve as the coordinator of Technology Committees. I also referee manuscripts for the Journal of the Acoustical Society of America and, in the past, have refereed for the Australian Acoustical Society as well.
