What we do

The diversity of animal behavior is fascinating, yet we know little about how behavior evolves.
We take genetic, genomic, molecular, and neurobiological approaches to understand the mechanisms underlying the natural variation and evolution of behavior.
Our work focuses mostly on the evolution of exploratory and social behaviors – like pair bonding and parental care – in Peromyscus mice.
