Acoustic Sensing in the Ocean

Sound is the best information carrier in the ocean. Working at the intersection of physics, engineering and biology, I develop computational methodologies and interpretation frameworks to extract and exploit biological information from ocean acoustic data across multiple spatial and temporal scales. My goal is to use this information to uncover functional relationships at mid to high trophic levels in the marine ecosystems. My current research focuses on integrating physics-based models and data-driven methods to address two fundamental aspects of acoustic sensing:

  • Sampling – how do we collect better data?
  • Inference – what can we learn from the data?

A parallel but closely related focus of my research involves using echolocating animals, such as bats and toothed whales, as biological models to inspire adaptive sensing strategies for autonomous distributed ocean monitoring.

My research program is funded by the National Science Foundation, the Office of Naval Research, and the National Oceanic and Atmospheric Administration.
