  He joined ARL in 2013. His current research interests at ARL are in machine learning for underwater applications, bio-acoustics and signal processing in impulsive noise. Applications span fields ranging from shallow tropical waters infested with snapping shrimp noise, to the depths of the ocean, to the Arctic ice sheets where glacier melt noise dominates the soundscape. His Ph.D research involved the development of improved algorithms for underwater signal processing. These included detection & localization, acoustic propagation modeling and vector sensor processing, and developing robust methods in impulsive noise.

Research Fellow

Line: 9 to 9
  He joined ARL in 2013. His current research interests at ARL are in machine learning for underwater applications, bio-acoustics and signal processing in impulsive noise. Applications span fields ranging from shallow tropical waters infested with snapping shrimp noise, to the depths of the ocean, to the Arctic ice sheets where glacier melt noise dominates the soundscape. His Ph.D research involved the development of improved algorithms for underwater signal processing. These included detection & localization, acoustic propagation modeling and vector sensor processing, and developing robust methods in impulsive noise.
