From basic foundational concepts to advanced topics in modeling the statistics of echoes from discrete scatterers, inspired by sonar observation of marine organisms.
J. Acoust. Soc. Am., 2018

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.
J. Acoust. Soc. Am., 2018

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.
PLoS Bio., 2017

The weak but persistent echoes from the hindwing tails of luna moths may help them confuse the sonar-guided bat predators, even though the tail echoes themselves are not strong enough to completely distract the bats’ attention.
J. Acoust. Soc. Am., 2016

Broadband echo statistics model can achieve a similar level of performance as conventional energy-based methods, such as echo integration, in estimating the numerical density of fish observed using sonar in the ocean
