Troy Murphy

Troy Murphy is a Professor in the Biology department at Trinity University, San Antonio, where he teaches Animal Behavior, Integrative Biology, and Methods for Biological Problem Solving. His active research program and community partnerships, including recent university news coverage (2020-2021), confirm his current faculty status.

His educational background includes:

• Ph.D. from Cornell University
• B.S. from the University of Arizona

Dr. Murphy's research centers on evolutionary biology and behavioral ecology, specifically investigating social signaling and the evolutionary maintenance of elaborate characters in animal communication. He combines comparative studies with field and aviary-based behavioral research, primarily using birds (goldfinches, motmots, orioles) and fish as model organisms. A key focus is understanding whether female ornamentation is adaptive and how such traits function in status signaling versus mate attraction—a historically understudied area where his work has contributed significantly to recognizing female signaling in evolutionary contexts.

Analysis of his publication record reveals consistent exploration of carotenoid-based coloration, bill signaling, and tail displays across avian species. His work demonstrates how traits like bill color in American goldfinches serve as dynamic status signals, while motmot tail-rackets indicate condition dependence with notable sex differences. This research challenges traditional sexual selection paradigms by highlighting female-specific signaling mechanisms.

No specific scientific awards are mentioned in available materials, though his publications in high-impact journals like Proceedings of the Royal Society B and Animal Behaviour reflect scholarly recognition.

Dr. Murphy actively mentors undergraduate researchers, guiding them through honors theses and co-authoring publications. Students regularly accompany him on 6-8 week summer fieldwork trips to Canada and Mexico. His lab emphasizes inquiry-based learning where students conceptualize frameworks, conduct experiments, and present findings at national conferences. He also partners with Northside ISD middle schools in a Purple Martin monitoring project, bringing scientific research directly to campus nesting colonies.

His laboratory program spans ecology and evolutionary biology, with ongoing field and aviary studies of avian communication systems. The partnership with local schools exemplifies his commitment to community engagement, using campus-based martin colonies to provide K-12 students with real-time exposure to scientific processes.
