PROSPECTIVE STUDENTS
I am on sabbatical during the 2023/24 Academic Year, so will not be taking on any new undergraduate or graduate students this year. If you are a graduate student interested in beginning in Fall 2024, please send me an email with a CV or resume, research interests, and a writing sample.

Kerry Byrne (PI)
When Kerry isn't teaching and helping students with research projects, she enjoys being outdoors with her husband, daughters, and border collie, Zea mays. She loves backpacking, trail running, and cooking tasty new dishes in her spare time. Two recent adventures were hiking the John Muir trail (solo) in 2014 and backpacking the Walker's Haute Route in France and Switzerland in 2016. Since then, her adventure has mostly been working full time while raising two young children during the pandemic.
Current Graduate Students

Francisco Chavez joined the lab in June 2021, after graduating from HSU with a B.S. in Environmental Science and Management with an emphasis in Ecological Restoration and a minor in Botany. He managed to complete his 4-year degree right after high school in 3 years!
As a graduate student, he is monitoring the recovery of sagebrush steppe plant communities after a 4-year experimental drought and determining if a legacy effect is evident within the communities. This project requires that he looks at different components of the plant communities, such as aboveground and belowground biomass, seed bank composition, and species composition. His research will help contribute to areas of sciences that do not receive a lot of research attention.
During his free time, Francisco enjoys baking with his roommates, playing video games with his friends, and zoning out on long runs while listening to his favorite songs.

Jules Bartley, M.S. '23
Jules successfully defended their thesis "Physical characteristics and fine roots within duff mounds of old-growth sugar and Jeffrey pine in a fire-excluded Sierran mixed-conifer forest" in summer 2023 and currently works for the Forest Service FIA Program in Washington.
Sean Stewart, M.S. '23
Sean successfully defended his thesis "Insights into the conservation of the rare perennial herb, Astragalus applegatei" in spring 2023 and is currently applying for jobs and working on publishing his thesis.
Allison Nunes, M.S. '21
Allison successfully defended her thesis "Seed bank composition within two sagebrush steppe communities: a comparison of drought and microsite effects" in summer 2021. Her research was published in Journal of Arid Environments in 2022. She currently works as an Associate Ecologist for Jodi McGraw Consulting.
