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 Ph.D. candidate studying the intersection of forest entomology and fire ecology. Her research explores the effects of mixed severity wildfires across temporal scales on pollinating bees, beetles, and flies in eastern Washington. She uses both field based and molecular methods to answer questions about pollinator community composition, bee fitness, and plant-pollinator networks. Prior to her graduate studies, Autumn worked as an environmental educator for a non-profit school. She also served in AmeriCorps as a full time farm-to-school program coordinator. Engaging in accessible science communication and education remains a central goal for her professional career.

Gissella Quiroga

Gissella is an M.S. student studying the effect of balsam woolly adelgid in the Pacific Northwest, and the basis of host tree resistance balsam woolly adelgid in the Gifford Pinchot National Forest. Gissella graduated from Cal Poly San Luis Obispo with a B.S. in Forestry & Natural Resources and Environmental Management & Protection in 2021. She has since worked for CalFire’s Jackson Demonstration State Forest and then Inland Empire Resource Conservation District.

Marlee Theil

Marlee is an M.S. student interested in the spatial and temporal trends of invasive species and how these trends are altered by climate change and urbanization. Her goal is to utilize her research to develop management strategies and restoration plans to protect the forests of the Pacific Northwest. She earned her B.S. in Environmental Science from Slippery Rock University in Pennsylvania, where she studied water quality of freshwater systems through biological and chemical assessments. She has experience working with invasive plants throughout western Oregon, and researching invasive wildlife in southern Florida.
