A major challenge in biology is to understand the causes and consequences of variation among individuals in their behavior, morphology, and physiology (i.e. their phenotype). It is becoming clear that past and current environmental influences (e.g. predation risk, density of conspecifics) can cause even genetically identical individuals to appear and behave in markedly different ways. I am an integrative biologist who uses fish as a model system to understand how plasticity, both within and across generations, drives phenotypic change in response to variation in the social and ecological environment. To answer these questions, I work at the intersection of behavior, evolution, and ecology using field and laboratory experiments, molecular tools, and physiological manipulations.

Our recent TREE paper shows the unique role of transgenerational plasticity in generating both adaptive and maladaptive responses to human-induced environmental change

I organized a symposium on phenotypic plasticity and Christian presented a poster on his independent project at Behaviour 2019!

I recently finished my third field season examining cooperative dynamics and paternal care in wild ocellated wrasses with Suzanne Alonzo

Check out my data nugget on one of my dissertation chapters. See here for information on data nuggets and their use in the classroom!

In my new preprints, I show that paternal experiences are distinct from maternal effects and persist for multiple generations in a lineage and sex-specific way

Congratulations to Eunice for being awarded high distinction for her honors project on different types of paternal cues!

Check out our recent review on multigenerational patterns of transgenerational plasticity! 

Congrats to Marion on her paper showing that stickleback males independently use olfactory and visual cues during courtship to assess a female's history with predation risk!
