My current research involves measuring plant-pollinator functional traits to better understand their interaction patterns. Further investigation of the ecological niche of native bee species using network and response-effect trait frameworks will help inform strategies to promote pollinator diversity, especially in the context of agricultural sustainability.

I am broadly interested in how organisms time their life cycle events in the context of changing environments. I am particularly interested in investigating these questions in bumble bees, as many elements of the bumble bee life cycle remain a mystery. My current research focuses on exploring the variation in timing of colony activity, reproduction, and dormancy in the yellow faced bumble bee (Bombus vosnesenskii) across its range. Ultimately, I hope to use natural history and ecological research to inform conservation. Prior to coming to UC Davis, I began my graduate work with Elizabeth Crone at Tufts University and I am now co-advised in the Crone and Williams labs.

I am interested in how global change impacts solitary bees. For my dissertation work, I am integrating variables across multiple spatial scales to understand how rapid environmental change affects reproduction and habitat selection in the blue orchard bee, Osmia lignaria. My previous research was primarily focused on bee community ecology. Throughout my master’s, I studied how bee diversity and community composition changed over time at Pinnacles National Park. During my bachelor’s, I monitored and compared bee communities in native and restored habitats at the Albany Pine Bush Preserve.

Broadly, I am interested in how land management choices impact pollinator communities and the steps that can be taken to better support robust communities, especially in agricultural settings. In my undergraduate thesis, I explored the impacts of local and landscape resources on bee biodiversity in semi-arid Texas pumpkin agroecosystems. I hope to investigate similar questions in California agroecosystems.
