Raina Margaret Maier is a Professor at the University of Arizona (since 2000), specializing in environmental microbiology and bioremediation. Her research focuses on microbial processes in extreme environments, phytostabilization of mine tailings, and applications of biosurfactants. She has advised numerous graduate students, including Karen Serrano, Lydia Jennings, and Priyanka Kushwaha, who have received awards for their work. Key honors include the 2022 Women of Impact Award, 2017 Women of Influence Mentorship Award, and a 2014 Leading Edge Researcher Award. Her educational background includes a Ph.D. in Microbiology from Rutgers University (1988) and a B.A. in Biology/Chemistry from the University of Minnesota (1983). She has taught courses such as Environmental Microbiology (ENVS 425/525) and Mine Reclamation (ENVS 696c). Her work integrates microbial ecology with environmental engineering, addressing challenges in contaminated site remediation and arid ecosystem sustainability. Recent research highlights include: soil biogeochemistry in mine reclamation (2025), microbial-plant interactions in guayule crops (2024), and biosurfactant-based metal recovery (2023). Her articles span topics like uranium remediation (2022), hyperaccumulation genetics (2022), and arid soil microbiome dynamics (2020). Current projects involve community science data integration (2021) and critical metal recovery from aqueous sources (2021). Grants and collaborations include funding for phytostabilization trials, surfactant synthesis, and environmental justice initiatives. She leads interdisciplinary teams at the University of Arizona, focusing on bridging microbial science with practical environmental solutions.
