Ryan Garrison

Ryan is a Ph.D. student studying the interactions between non-native insect herbivores and their host plants, and he is particularly interested in the use of Arboreta, including the Washington Park Arboretum, in research. Ryan earned his B.S. degree from Michigan State University, and he earned his M.S. degree from the University of Washington studying the invasive azalea lace bug on Rhododendron spp. in western Washington. In addition to his graduate studies, Ryan is also a Plant Health Specialist with the University of Washington Botanic Gardens.

Autumn Maust

Autumn is a M.S. student who received her B.S. in Natural Resources from the University of Vermont in 2018. As an undergraduate, she had the privilege to participate in conservation projects in New England and New Zealand. Prior to entering graduate school, she worked as an outdoor educator and encouraged students to engage in environmental stewardship while gardening, beekeeping, and exploring. Broadly, her research interests include entomophily, insect ecology, native landscape restoration, and disturbance ecology. Autumnís research project will discuss the effect of disturbance on established forest pollinator populations.

Alex Pane

Alex is a Ph.D. Candidate who earned a B.S. in Integrative Biology from the University of Illinois, researching the nesting ecology of ground dwelling bees. With a taste for field research and a love for the outdoors, Alex moved west to pursue graduate work in the School of Environmental and Forest Sciences. In his time climbing and hiking, Alex has always come back to the same broad question: why do insect disturbances occur in some locations but not others? The iconic forests of the Pacific Northwest have been the perfect system to begin exploring this question, with insect disturbances occurring over highly variable spatial and temporal scales. His research focuses on identifying how native forest insect disturbances have changed in recent decades across the Pacific Northwest. Using long term regional data sets and intensive field sampling, Alex hopes to provide a better understanding of the processes driving these outbreak patterns and how they may shift as the climate continues to change.
