Dr. Ivey studies the evolution and ecology of plants and insects. His work focuses on plant-insect interactions, the evolution of mating systems, reproductive ecology, and plant defense. His current projects include studies of genetic variation and phenotypic selection of mating system and physiological traits in Clarkia and Mimulus, identifying patterns and mechanisms of speciation in Mimulus, and testing how induced anti-herbivore defenses alter sex allocation in Mimulus guttatus.
