Heather Brooks
Ethologist, Postdoctoral Associate
I earned my PhD in 2025 from the University of Tennessee, Knoxville, and I am currently a postdoc at the University of Colorado Boulder in the Peleg Lab. I am broadly interested in animal behavior, animal communication, complex social systems, and human-animal interactions.
Research Interests

My research interests have always been tied to conservation efforts and maintaining global biodiversity. I discovered the field of animal behavior at the University of Illinois and have pursued this passion ever since. I am particularly interested in mixed-species communication and behavioral interactions. This includes dominance relationships, playful interactions, and acoustic communication between species. I have collected behavioral data on terrestrial mammals, aquatic mammals, fish, and songbirds.
​
My doctoral work focused on communication in mixed-species flocks of Carolina chickadees and tufted titmice in East Tennessee forests. I examined whether communication, particularly vocal output, could be considered a behavioral syndrome or personality trait in these species. Most recently, I have been studying visual systems and communication in various firefly species as well as cognitive and behavioral measures in other insects, such as honeybees.
