I am a bumble bee ecologist interested in how anthropogenic changes to the landscape and environment (e.g., agriculture and climate change) impact bumble bee behavior, colony growth and reproduction, and populations and communities. My PhD research sought to develop an understanding of how common species such as the common eastern bumble bee (Bombus impatiens) cope with variable floral abundance brought about by agroecosystem management (e.g., mass-flowering crops), while also exploring the diverging population patterns of Midwestern bumble bee species in response to agricultural intensification using historical databases of agricultural statistics and bumble bee records. Overall, the goal of my work is to improve our understanding of the factors that allow some bumble bee species to succeed while others struggle in hopes to develop more robust conservation strategies for bumble bees.

I am interested in wild bee conservation in the light of impacts of multiple stressors pollinators encounter in their environment. My current research addresses the scarcity of foraging resources. I am involved in testing different plant species mixes for pollinator habitat restoration in an agriculturally dominated landscape of the Californian Central valley. In my PhD at the Free University of Berlin I worked on threats of wild bee health by pathogen exposure from infected honey bees and studied Osmia bicornis and Nosema ceranae as a model system. Furthermore I contributed to recommendations for practical pollinator management in urban environments.

Developing best management practices for cover crop systems in Almond
Email
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.

Conservation, biodiversity, functional traits, interaction turnover

My interests range from basic bee and plant biology to community ecology and ecosystem function. I am particularly fascinated by how species interact as members of complex networks, how individuals accumulate into populations and communities, and how species play different roles within ecological communities. My previous work has focused on the co-flowering phenology of montane wildflower communities, phenology and diversity of Rocky Mountain bee species, and characterizing a bipartite plant-pollinator interaction network across time. I hope to explore the spatiotemporal dynamics and ecosystem functional roles of various plants and pollinators within natural plant-pollinator networks. Megachile relativa is one of my favorite native bee species.

I am broadly interested in pollination ecology and pollinator conservation in applied agricultural settings. My previous research has included developing a solitary bee monitoring program for the Bernard Field Station (Claremont, CA) and investigating whether some insects are more effective at pollinating
Echinacea angustifolia than others. My dissertation research focuses on using plant-pollinator interaction networks to (i) assess the impact of honey bee introductions on native plant pollination and (ii) optimize wildflower plantings to simultaneously support managed and native bees.

Bee ecology, agroecology, environmental stressors, pesticides, nutrition

I am interested in the direct and interactive effects of environmental stressors on native bees. Specifically, I focus on nutrition and pesticide exposure and their comparative effects on Osmia lignaria and Bombus vosnesenskii fitness, health, and behavior. Previously, I studied native bee communities in blueberry fields and the response of bumblebee colonies to insecticide drift. I also studied the risks bumblebees face by both floral resource scarcity and an endoparasitoid conopid fly using an RFID system.

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.

Pollination biology, global change, community ecology, plant mating systems

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.
