Introduction
I am a PhD candidate in the Ecology, Evolution, & Behavior graduate program at the University of Texas at Austin. My research focuses on evolutionary questions, particularly what factors contribute to the rapid evolution of conspicuous traits in lineages. I am experienced in field research, behavioral analysis, visual modeling techniques, hormonal assays, and cloning techniques. In addition to my dissertation research, I also work as a graphic designer and exhibit planner for the Texas Natural Science Center, designing a new exhibit on the relevance of evolution to peoples' daily lives.

Aposematic signals represent one of the most accessible traits to evaluate the interaction of natural and sexual selection on signal evolution. Here we investigate the contributions of these two selective forces on the aposematic signal evolution of the highly polytypic strawberry poison frog, Oophaga pumilio, of Bocas del Toro, Panama. Previous re...

Though theory predicts consistency of warning signals in aposematic species to facilitate predator learning, variation in these signals often occurs in nature. The strawberry poison frog Dendrob- ates pumilio is an exceptionally polytypic (populations are pheno- typically distinct) aposematic frog exhibiting variation in warning color and brightnes...
Article

Many species use conspicuous "aposematic" signals to communicate unpalatability/unprofitability to potential predators. Although aposematic traits are generally considered to be classic examples of evolution by natural selection, they can also function in the context of sexual selection, and therefore comprise exceptional systems for understanding...

Aposematic (warning) coloration is a highly conspicuous trait that is found throughout the animal kingdom. In several aposematic species, warning signals have been co-opted for use in conspecific communication systems; for example, in the toxic and bright orange Solarte population of the strawberry poison frog (Oophaga [Dendrobates] pumilio), the b...
