Seismic signal production in a wolf spider: parallel versus serial multi-component signals
The selective pressures that may drive the evolution of multiple sound-producing structures as well as the selective pressures in the production, processing and evolution of multi-component signals are discussed.
A precedence effect resolves phantom sound source illusions in the parasitoid fly Ormia ochracea
The precedence effect is demonstrated as a mechanism to overcome phantom source illusions that arise from acoustic reflections or competing sources, and flies preferred phonotaxis to a forward source.
The start of phonotactic walking in the fly Ormia ochracea: a kinematic study
Differences in the amplitude of rotational velocity as a function of source azimuth determine the directional orientation of phonotactic responses, similar to a neural measure of auditory directionality (interaural latency).

Are Centrally Displaying Males Always the Centre of Female Attention? Acoustic Display Position and Female Choice in a Lek Mating Subterranean Insect
Testing the prediction of the central advantage model in investigating the importance of male display position in the subterranean and lek mating prairie mole cricket (Gryllotalpa major), it was found that in general, female attractions were distributed randomly across the lek; male attractiveness was not related to proximity to the leK centre nor to any factor associated with display position.

This study provides a foundation for further work on the biomechanics and neural mechanisms of spatial hearing in H. chrysoscelis, and lends valuable perspective to behavioral studies on the use of spatial information by this species and other frogs.

My research investigates sensory mechanisms involved in these auditory processing tasks of an insect hearing specialist, to isolate individual sound sources of interest over noise to support the idea that the ears of O. ochracea function as bilateral symmetry.

This study revealed that in Floridian Ormia ochracea, the pulse rate preference function is not affected by the locomotor mode (walking vs flying) used in phonotaxis, and describes for the first time, pulse rate selectivity in Californian Ormia Och racea.
Nonlinear processing of a multicomponent communication signal by combination-sensitive neurons in the anuran inferior colliculus
This work investigated how female green treefrogs (Hyla cinerea) integrate the multiple spectral components present in male advertisement calls, consistent with the hypothesis that nonlinearities play potentially critical roles in spectral integration and in the neural processing of multicomponent communication signals.
