Hari Vishnu

Hari is a Senior Research Fellow at NUS working on underwater acoustic signal processing and machine learning. These are used in a range of applications ranging from bio-acoustics based biodiversity characterization and defense-related scenarios in shallow tropical waters, to polar glaciers where melt-induced cryo-acoustic noise dominates the soundscape. From 2019, he is focusing on the acoustics of melting ice, and undertook field campaigns to Svalbard in the Arctic, and to the Antarctic to study this problem. He also studies distributed acoustic sensing, and acoustics based marine-mammal and reef health monitoring. He obtained his PhD from NTU in 2014 and was a Visiting researcher at Scripps Institution of Oceanography during 2019-2021.
