In my courses, in addition to learning cool and important information about psychological science, animal minds, evolution, and the biology of behavior, you'll develop critical and scientific thinking skills that will continue to be useful throughout college and beyond, regardless of your major.

I am interested in vocal communication, emotion, and evolution in humans and animals, and I investigate this by looking at both the production and perception of vocalizations. The production component involves observing and recording animals, to investigate the relationships between emotion and acoustic characteristics (such as pitch or duration) of their vocalizations. The perception component entails testing whether and how human participants perceive emotion from animal calls. The ultimate goal of this work is to gain insight into how emotions generally affect the evolutionary history and tragectory of vocal communication.

Given my interest in animals’ emotions, I am also passionate about animal welfare. Before obtaining my M.A. degree, I volunteered at a howler monkey sanctuary in Panama, and have published on best practices for primate rehabilitation.
