After growing up in Ann Arbor, MI, I relocated to Denison University in Granville, OH to pursue my undergraduate degree. Though I began my college career as a Studio Art major, I quickly found that biology was my calling. I studied a wide range of systems throughout college, from lemon sharks and rock iguanas to deciduous shrubs. I am now conducting research on insect color and behavior in the Animal Behavior program at UC Davis. When I’m not obsessing over bugs, I can usually be found spoiling my pet chickens, drawing sketches for The Ethogram, or writing poetry.
Color is a visible fingerprint of the built-in complexity of ecological systems. The diversity of animal color patterns in nature reflects their many functions; color can help organisms avoid predators, attract mates, mitigate abiotic stressors, and more. In my research, I aim to demonstrate how animals integrate multiple, often conflicting selection pressures on coloration, using swallowtail larvae (family Papilionidae) as a model system. My work combines concepts and methods from several fields – particularly ecology, animal behavior, physiology and biological timing (phenology) – with my background in the visual arts to answer fundamental questions about the complexity, diversity, and ecological roles of color in animals.
