Professor Juenger's research focuses on the interface of ecological and evolutionary processes in natural plant populations. In particular, he is interested in the evolution of adaptive phenotypic plasticity in response to biotic (herbivory) or abiotic (drought) stress. His approach has combined ecological manipulations in the field, quantitative genetic experiments, and modeling analyses to gain a variety of perspectives on how ecologically-important plant traits evolve. His future research will integrate ecological, evolutionary, and molecular genetic methods in more detailed studies of plasticity. This work will center on evaluating natural selection imposed by environmental stress at both phenotypic and molecular levels using Arabidopsis as a model system.
