I am broadly interested in agroecosystem diversification and how research can work in tandem with other forms of knowledge and expertise to build capacity for enhanced multifunctionality in agricultural systems. Prior research has focused on the intersection of cover crops and soil health. Currently, I am working with growers, researchers, advisers and non-profits to develop a set of best management practices for integrating cover crops into almond orchards.

 I am interested in plant-pollinator interactions in the context of floral reproduction. Primarily, I am interested in how drivers of global change (e.g. climate change and species invasion) alter phenological timing of plant-pollinator interactions and whether this matters in the context of plant mating system/life history strategies. For my MSc work I studied how the introduced bumble bee Bombus terrestris displaces the native Patagonian bumble bee Bombus dahlbomii’s interaction with Fuchsia magellanica through nectar robbing, and how such nectar robbing alters plant female reproductive success throughout the entire reproduction process.

I am interested in integrating tools and perspectives of landscape ecology to promote pollinator diversity in the context of agricultural sustainability. This will involve a more holistic multifunctional understanding of pest and pollinator populations, communities and management in working landscapes.

I am broadly interested in the intersection of urban landscape ecology, pollinator conservation, and population biology. Specifically, I am curious how variables associated with urban development, like pollutants, heat, and imperviousness, lead to changes in mason bee (Osmia lignaria) population dynamics and health. My previous work has been primarily focused on bee community ecology. In 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.

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.
