My research interests address how changes in the abiotic environment affect plant-pollinator interactions and plant reproductive output. I start with basic questions like: (1) What is the life history and phenology of this plant species? and (2) What pollinates this plant species? Once I have answered those basic questions, I can move on to more complex questions like: (1) How does disturbance affect a plant species’ reproductive patterns? and (2) Will the timing of floral visitations synchronize with the timing of plant flowering? My work has taken place in the Brazilian Amazon, south Florida pine rocklands, Alaskan tundra, and Colorado Rockies.
