Chris Oliveras, PhD
Assistant Professor,
Civil and Environmental Engineering, UC Irvine

Chris Oliveras (he/él) is an Assistant Professor at the University of California-Irvine in the Department of Civil & Environmental Engineering. He researches the interactions between microorganisms and organic pollutants (e.g. per- and polyfluorinated alkyl substances - PFAS), and how these interactions are shaped by wildland-urban interface fires and other climate change disasters. His research team employs analytical chemistry, applied microbiology, and environmental data science tools to develop remediation strategies that can safeguard water quality. He is also committed to environmental and climate change literacy programs. Chris obtained his PhD. in Environmental Engineering and M.A. in French at the University of Arizona.


Joanna Solins, PhD
Environmental Horticulture Advisor
UC Cooperative Extension Sacramento, Solano, and Yolo

Joanna Solins is an Environmental Horticulture Advisor for UC Cooperative Extension, serving Sacramento, Solano, and Yolo Counties.
