Research and Practice Interests

Reproduction is a social interface that intertwines the fates of males and females. I study the traits important to this evolutionary interface, from elaborate courtship displays and strong mate preferences to post-copulatory interactions between male and female reproductive proteins. I am interested in understanding 1) the co-evolutionary dynamics that generate diversity in reproductive traits, 2) how natural and sexual selection interact to produce different male and female phenotypes, and 3) how trait expression is shaped by the life histories of individuals.

To understand these fundamental issues, I study butterflies and jumping spiders. This choice is motivated by a lifelong fascination with the lives of these tiny animals, but also supported by their exuberant diversity and experimental tractability. My research group uses techniques from visual ecology, psychophysics, behavioral ecology, evolutionary genetics, nutritional ecology, phylogenetics, and the “omics”. We strive to understand the big picture by focusing on the details. Our goal is to uncover the evolution of underlying mechanisms.

Communicating our results to the public is also an essential part of our scientific practice. We support scientific curiosity and literacy in our local communities through collaborations with local schools, informal educational partners, and via social media. I am particularly interested in art-science collaborations and the novel insights they can provide into the human experience.
 
Current projects in the lab include:
 
1) Co-evolution of complex male displays and female visual attention in Habronattus jumping spiders
2) The causes and consequences of repeated evolution of jumping spider color vision
3) Interactions between color vision and depth perception in jumping spider visual ecology
4) Antagonistic and cooperative co-evolution between male and female reproductive proteins in pierid butterflies
5) Pre- and post-copulatory reproductive isolation during incipient speciation in the butterfly Pieris rapae
6) Nutritional ecology and evolution of the life history architecture of P. rapae
