Current Areas of Research

I am interested in how sensory perception and cognitive processing influence the evolution of animal behaviors. I use behavioral experiments to determine how animal communication signals and strategies evolve under the influence of receiver psychology, focusing on features such as memory and discrimination. Recent work examines the broad behavioral impacts of proportional psychophysics—how the nervous system translates physical stimulus magnitude into a perceived amount. I have applied many of these concepts to anuran acoustic communication and mating behavior, and I am now focusing on cephalopods. Current projects analyze interactions based on the visual chromatophore patterns that characterize squid mating behaviors and cuttlefish feeding behaviors.
