Sierra nevada ecology, urban ecology, conservation biology, plant evolutionary ecology, solitary bee population and community ecology, monitoring, climate change in alpine environments

I am interested in both the evolutionary ecology of plants and the conservation of their pollinators. My lab focuses on the effects of climate change on bumble bee species in alpine environments as well as the effects of urbanization on wildlife. I direct the Great Sunflower Project, a citizen science project, designed to evaluate the effects of landscape change on pollinator service in North America.

My lab works in areas as diverse as the northern Sierra Nevada mountains, San Francisco city parks, Andes of Ecuador and vineyard areas of California. We also work on developing effective and cost-efficient ways to monitor bees and other wildlife. I am also interested in the effects of variation in flower phenology on plant reproductive success and the evolution of flowering time. We use Linanthus dichotmous, a plant that flowers during the day north of San Francisco and at night south of San Francisco, as a model system.
