The Ecology and Evolutionary Biology Department recognizes that Black Lives Matter. As scientists, we reject the notion that science is separate from societal issues and inherently non-racist. We are committed to ending anti-Black racism and police violence against Black communities. We pledge to abolish white supremacy in all its forms and to elevate Black excellence in our department, the School of Biological Sciences, UC Irvine, and beyond.

Masters and PhD programs offer preparation for diverse career paths in an inclusive community with excellent mentoring and graduate support.

Research in EEB

Faculty and trainees have access to world-class research facilities from the latest genetic sequencing technologies to an unparalleled network of field sites distributed across California’s diverse ecosystems.


UC Irvine evolutionary ecologists are teaming up to save rare plants from extinction in Hawai‘i.

Basic research in plant evolution can be coupled with efforts to conserve very rare Hawaiian plant species, as shown in this video produced as part of the public outreach of an NSF-funded collaborative project. This research employs field, greenhouse, and genomic approaches to study phylogenetic relationships and the importance of gene flow, hybridization, and reproductive barriers with changes in breeding systems in the adaptive radiation of Hawaiian Schiedea.
