ECOLOGY AND EVOLUTION OF INSECT-MICROBE SYMBIOSIS
Welcome! I am an ecologist, entomologist and microbiologist fascinated by the evolution of macrobe-microbe interactions, especially symbiosis. Although much of the rapidly growing field of microbiome research is focused on humans and other mammals, nowhere are the forms and functions of symbiosis so diverse as among the insects. My work focuses on bees and Lepidoptera (butterflies, moths, and their larvae), two ecologically and economically important groups that have intricate, but also quite variable relationships with microbes.
The study of insect-microbe interactions has led not only to exciting and unexpected discoveries about the natural world, but also to information and tools useful for managing agricultural pests, supporting pollinators, and controlling disease vectors. Furthermore, in our current era of rapid global change, knowledge of microbiomes will be increasingly important for sustaining macrobial biodiversity. Insect declines in particular are a pressing concern, yet we don't have a good handle on whether, and if so how, microbes might mediate insect responses to anthropogenic stressors.
My dissertation research in Noah Fierer's lab and Deane Bowers' lab at CU Boulder integrated field collections, microbial community profiling and metagenomics, insect rearing and experiments, and natural history. I recently began a postdoc in Nancy Moran's lab at UT Austin, where I am using comparative genomics, bacterial culture-based assays and genetic engineering, and in vivo experiments to study the evolution and function of gut microbiomes of social bees.
