Research Interests

Broadly speaking, I study behavioral responses to environmental change, most often human-induced environmental change. Within this context, I’m interested in how both evolutionary and developmental histories have produced the sensory systems and behavioral ‘rules of thumb’ that animals use to interact with their environments.

I study these questions both experimentally and with theory. The empirical system that I’m currently most involved with uses the Trinidadian guppy to study sensory systems and behavior in response to novel predator cues and increasing turbidity in Trinidadian streams. I’m also using signal detection theory and bet hedging theory to model behavioral responses to environmental change.
