Ecology, Evolution and Behavior
Environmental variation is ubiquitous. Learning and phenotypic plasticity play a crucial role in allowing organisms to cope with such variation. Understanding why organisms vary in the degree of plasticity is important to predicting how species will respond to human-induced environmental change, such as global warming, the spread of non-native species, and habitat conversion. My research focuses on the idea that the developmental mechanism of plasticity determines the costs and constraints of plasticity. Taking a developmental approach yields important insights into understanding the evolutionary conditions favoring plasticity.
I am primarily interested in the evolution of learning, focusing on topics such as the costs of learning and information acquisition, and the role of developmental timing and nutrition as constraints on the evolution of learning. Some of my research considers the role of relaxed selection as a limit on the evolution of alternate developmental pathways. I am also interested in how species respond to novel and changing environments, including the role of learning and plasticity in this process, and the effects of behaviorally mediated cryptic genetic variation.
