David A Gray

David A Gray is a Professor in the Department of Biology at California State University, Northridge, specializing in behavioral and evolutionary mechanisms of acoustic communication in insects and amphibians. His work bridges field observations with molecular analyses to examine speciation, sexual selection, and environmental impacts on signaling systems.

Education:

• Ph.D., 1997, University of New Mexico
• B.A., 1992, University of California Santa Cruz

Gray's research centers on cricket communication systems (particularly Gryllus species), exploring how temperature, geography, and predation shape acoustic signals and mate choice. His work extends to frog aposematism and cross-species comparisons of sexual selection. Key themes include eavesdropping dynamics, phenotypic plasticity in vestigial traits, and genomic underpinnings of behavioral divergence, reflecting an integrative approach from molecular to ecological scales.

Analysis of his 15 most recent publications (2018-2024) reveals consistent focus on acoustic communication in field crickets, with expanding integration of genomics (e.g., genome assembly of G. longicercus) and biogeographic analyses. His work increasingly examines temperature-mediated effects on signaling and the cognitive mechanisms of mate choice across taxa.
