My research is in the area of acoustical oceanography, that is, studying the physics and biology of the ocean, and their interactions, through the use and development of acoustic techniques. The specific areas of research that I am involved in include 1) acoustic scattering by marine organisms, such as zooplankton, micronekton, fish, and squid, 2) acoustic scattering from physical process that occur in the ocean interior, such as oceanic microstructure, turbulence, double-diffusion, and internal waves, and 3) acoustic propagation in highly turbulent environments with dense bubble clouds, the impact of these physical processes on the propagation of mid- and high-frequency sound in shallow coastal environments, and implications to acoustic communications. To date, my research has been focused in coastal regions (shore ward of the continental shelf break) in water depths of less than 200 meters (e.g. the Gulf of Maine, Georges Bank, New Jersey Continental Shelf), as the natural abundance of zooplankton is high and turbulent dissipation rates and stratification tend to be high, resulting in strong acoustic signals from microstructure.
My research approach encompasses the theoretical development of analytical physics-based models to understand the scattering and propagation of high-frequency sound in the ocean, laboratory experiments to verify acoustic models in a controlled environment, and in situ field experiments that make use of the models and allow the physics and/or biology of the ocean interior to be explored and better understood.
I recently developed a system to measure high-frequency broadband acoustic scattering during the generation, propagation, and dissipation of non-linear internal waves (press release). This system was deployed during a month long experiment over the New Jersey continental shelf, and the detailed analysis of the data acquired during this experiment is just beginning. I am developing a high-frequency broadband acoustic scattering system for deployment from an autonomous vehicle, a REMUS-100, in order to measure acoustic backscattering on temporal and spatial scales relevant to many physical and biological processes that occur in coastal regions.
Education and Outreach Information and Opportunties
There are opportunities for high-school students (WHOI Guest Student Program ), undergraduates (WHOI Summer Student Fellowship Program), graduate students (WHOI-MIT Joint Program), and post-doctoral students (WHOI Postdoctoral Fellow Program) in my laboratory. I am always interested in accepting applications from people with a background in physics, engineering, mathematics, or applied mathematics. I have advised students of many different levels and interests and continue to look for good students that share my research interests. If you are interested in research in my laboratory, in any of the above capacities, please contact me.
"Wave Scattering by Rough Surfaces and Randomly Inhomogeneous Media", a 12 unit MIT/WHOI Joint Program course that will offered next in Spring 2011.
