Research Interests

My dissertation focuses on the effects of phenotype and environment on movement behavior. I am particularly fascinated by factors that may contribute to an individual dispersing or remaining a resident; and the effects past and present environment may have on these behaviors.

Long distance dispersal movements are rare, with most individuals staying within their natal population. A growing body of literature identifying dispersal syndromes — suites of behaviors that are correlated across situations — suggests that dispersal does not involve a random sample of individuals. Rather, individuals that disperse are morphologically, physiologically, and/or behaviorally dissimilar from residents. These distinctions may result in differences in movement performance, habitat preference, genetic structure, response to density-dependence, and dispersal ability between residents and dispersers. By examining the fine-scale movements and behavioral responses of juveniles encountering habitat patches of varying quality as they depart natal sites, we can begin to predict patterns at larger ecological and spatial scales that affect local population and metapopulation dynamics.

Current Projects

(1)  Identifying a juvenile dispersal syndrome: contributions of phenotype- and condition-dependent factors

(2)  Influence of natal habitat on juvenile movement through delayed life-history effects

(3)  Spatially structured population dynamics of Ambystomatid salamanders
