Dr. Cox-Foster's focus is on understanding the mechanisms underlying host/pathogen interactions in honey bees and other pollinators. Her research utilizes a systems biology approach, examining the interactions at multiple levels including the molecular processes in the pollinator, the genomics of the pathogens, impacts on cellular physiology and immunity, and overall impacts on ecological interactions. Her work focuses primarily on honey bees and with extensions of the findings into other pollinator species. Her expertise includes the viral pathogens that infect bees and other pollinators and the impacts of varroa mites. She is also collaborating in projects to transition her research into application to remediate problems in honey bees and other pollinators, with emphasis on controlling viral disease via the mites and development of disease resistant bee strains.
