Research


My students and I conduct research on several aspects of monarch butterfly (Danaus plexippus) ecology. Our work has addressed their reproductive ecology, effects of investment in ejaculates by males on fitness and mating patterns in both sexes, a neogregarine protozoan parasite of monarchs, factors affecting the distribution and abundance of immature monarch stages, and risks posed by global climate change, insecticide use and genetically-modified crops. I have a strong interest in engaging K-12 students and teachers in inquiry-based science and promoting a citizenry with a high degree of scientific and environmental literacy. To this end, I have developed a comprehensive science education program called Monarchs in the Classroom. The program involves courses and workshops for teachers, a nationwide Citizen Science project called the Monarch Larva Monitoring Project, curriculum development, and distribution of monarch eggs and larvae to classroom teachers.
