Hyperparasites (parasites of parasites) can be helpful agents that reduce the impacts of disease. I am investigating how a fungal hyperparasite impacts powdery mildew infection. 

Native California Grasslands have been drastically altered through colonization and urbanization, experiencing compound threats of overgrazing, fire regime change, and invasion by European species. We investigate how the soil fungal community changes as a result of invasion and in response to ongoing restoration efforts. 

How might native plants influence invasions? Plants alter their local soil environment and subsequently affect plant growth through a process called plant-soil feedback. We ask if and how native species can influence the success of an invader (Genista monspessulana) through shared associations with soil symbionts.
