Education
- B.A., Human Biology, Stanford University, 1990

- Ph.D., Ecology, Evolution and Marine Biology, Univ. of California - Santa Barbara, 2001
Research Interests
Dr. Cummings is interested in identifying how the environment (social or physical) shapes the direction of evolution of animal sensory and signaling systems. Her research focuses on the evolutionary interplay between ecology and visual systems, and how this influences the direction of signal evolution (traits and behavior) through the processes of natural and sexual selection. She employs a number of different techniques to address this broad topic including optical measurements in the field, mate choice experiments in the lab, computational modeling of visual detection, physiological measurements of visual sensitivity (ERG, optomotor), and color pattern characteristics (spectral reflectance) of a number of different fish and frog species.
