My research program seeks to achieve a mechanistic understanding of the impacts of environmental change on plant-pollinator mutualisms, and to quantify the consequences of such impacts on biodiversity conservation and ecosystem function. To that end, I apply techniques from community ecology, functional ecology, population biology, molecular biology, and pollination biology to my studies in both natural and human-modified ecosystems. Currently, research topics at the forefront of my lab include impacts of climate change and invasive species on pollinator and plant ecology and evolution, pollinator conservation in novel (anthropogenic) ecosystems, managing of wild pollinators for agricultural pollination, and refining of techniques for effective monitoring of pollinator populations.

As a pollination biologist in the Oklahoma Biological Survey and the Oklahoma Natural Heritage Inventory, I am also working to construct an inventory and distribution map of pollinator taxa within the state of Oklahoma, starting with native bees.

I am currently recruiting graduate students! Please get in touch if you are interested in any of the topics above, or have a pollination-related topic of your own that you would like to investigate!
