Welcome to the DuVal Lab
Our research focuses on behavioral ecology, population genetics, and in the role of sexual selection in evolutionary change. Members of the lab study how multiple selective forces shape cooperation and competition in vertebrate groups, particularly birds. We also investigate how social context influences behavior. A developing research area applies machine learning tools to reduce human bias in quantifying interactions, allowing objective evaluation into how the multidimensional courtship displays of manakins relate to reproductive success and how they change over time.
The 2025-26 DuVal Lab
To date, many lab projects have used the lance-tailed manakin (Chiroxiphia lanceolata) as a model system. We also collaborate locally on research investigating cooperatively breeding brown-headed nuthatches (Sitta pusilla).
DuVal Lab Commitment to Community
We are committed to supporting excellence in biology by providing an environment in which everyone has the opportunity to learn and conduct research regardless of obstacles they may encounter along the way. We strive to develop a strong community within our lab to support lab members, and we also contribute to community-building within our department, university, and society in which we work. Communication with non-scientists is also a core part of our work.
