INTRO

As an educator, I consider my primary job to be to inspire students to learn and give them the tools necessary to successfully pursue their own interests. Consequently, I use a variety of techniques to get students interested in biology, from real world examples, activities, and stories. At LBC, I teach Biology II: Cell and Molecular Biology which gives students the foundational knowledge and skills necessary to pursue careers in biology. While I consider myself a broad naturalist with many research interests, I am primarily interested in understanding how phenotypic diversity evolves. I focus on animals that have aposematic coloration, or warning coloration. This coloration is meant to warn predators of secondary defenses, like toxins. Evolutionary theory predicts that predators should select for few, distinct signals to better learn, remember, and avoid them. But there are a number of examples of species that violate this assumption, with few being more enigmatic than the Neotropical Poison Dart Frogs. I use these as models to understand how predation, unpalatability, and learning result in relaxed selection allowing for a plethora of phenotypes to evolve. This, in turn, helps explain the vast diversity of colors and patterns we see in the natural world.
