Professional Memberships/Organizations


I’m a community ecologist focused on understanding how spatial processes influence community assembly, diversity, and function. I focus on theory-driven questions which I address through a variety of approaches that include strong field work and natural history components. I have recently finished my dissertation on avian-bryophyte dispersal networks in the Department of Biology at Portland State University in Portland, Oregon.

In addition to my research, I am enthusiastic about teaching, international collaboration, data literacy, and addressing equity imbalances in academia. I’m especially interested in how I can use my experience as a first generation citizen and college student to advise similar demographics.
