Plant-insect interactions and global change
Insects are declining globally, putting the services that they provide for humans and other organisms at risk. In Dr. Nicole Rafferty's lab at UCR, I study how plants, insects, and their interactions are being impacted by climate change and other stressors, and how to use that knowledge to improve conservation success and to protect ecosystem function and stability.
I mainly use moth pollination as a study system, and I have focused on California taxa and habitats. Moths are one of the most diverse groups of insects, and an integral component of terrestrial food webs. They are also important nocturnal pollinators, though they are vastly understudied in this regard compared to bees and other diurnal pollinators. This limits our ability to predict and manage the effects of climate change on moths and the services they provide. To help fill this knowledge gap, I use a variety of methods (including molecular biology techniques, controlled greenhouse studies, natural experiments in the field, and ecological network modeling) to address both basic and applied questions at scales ranging from functional traits to communities.

Heat and drought-induced shifts in plant circadian floral trait rhythms
In a greenhouse experiment, I investigated how temperature and water-stress altered 24-hour floral trait rhythms in a moth-pollinated plant. Our findings (in preparation) have implications for the timing and identity of pollinator visits in a changing climate.

Moth pollination networks through space and time
Using a steep elevational gradient in Southern California as a natural experiment, I have been sampling moth communities for three years and building plant-pollinator interaction networks using pollen DNA metabarcoding in order to examine how networks shift in space, time, and in relation to climatic factors.

Multilayer plant-pollinator, plant-herbivore networks
Leveraging a statewide dataset of Lepidoptera-plant pollination and herbivory interactions in California, I am analyzing how interaction patterns at multiple Lepidoptera life stages, and connections between network types, affect community stability and response to disturbances.
