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 mid- to high-trophic level biological information from ocean acoustic data across multiple spatial and temporal scales.
My current research focuses on integrating physics-based models and data-driven methods to address two fundamental aspects of acoustic sensing:
A parallel but closely related focus of my research involves using echolocating bats and toothed whales as biological models for adaptive and distributed ocean sensing.
I am an active contributor to open-source scientific software (see echopype), and have been the lead and co-lead of OceanHackWeek 2018-2021, a workshop dedicated to data science in oceanography.
My research program is funded by the National Science Foundation, the Office of Naval Research, and the National Oceanic and Atmospheric Administration.

We developd a data-driven methodology based on matrix decomposition to build compact representation of long-term echosounder time series using intrinsic features in the data.
Mid-frequency sonar provides a first-of-the-kind macroscopic observation of the nightly foraging runs of fish inhabiting a shallow-water artificial reef in northern Gulf of Mexico.
Experimental measurements and theoretical modeling provided insights into the mechanisms by which tongue-clicking fruit bats change their echolocation sonar beam direction without changing head aim or mouth shape.
A Python package that enhances the interoperability and scalability in ocean sonar processing.

Our echo statistics tutorial materials became the first ever JASA tweetorial today.
Super excited to host the special session Machine Learning and Data Science Approaches in Ocean Acoustics in the upcoming ASA/CAA joint meeting in Victoria, BC!
Data from the OOI cabled echosounders are perfect for watching the effects of a sonar eclipse in the ocean.
My second time sailing with the UW OOI Cabled Array team, with a mission to scoop up some zooplankton from the ocean.
