LAB DIRECTOR

Prof. Rebecca R. Hernandez

Associate Professor of Ecology and Earth System Science in the Department of Land, Air and Water Resources at the University of California, Davis

Prof. Hernandez is a global leader in research on environmental aspects of energy systems, identifying their impacts and development options to support a sustainable, just transition from fossil fuels to renewables. Prof. Hernandez has over 20 years of experience studying the land, air, water, biodiversity, and social impacts of energy development and how such impacts interface with global sustainability. She has led several studies published in Nature Sustainability, Nature Climate Change, Proceedings of the National Academy of Science, and Renewable and Sustainable Energy Reviews. Dr. Hernandez received her Ph.D. from Stanford University in four years and completed her postdoctoral training at UC Berkeley.

More recently, Prof. Hernandez and her group leads several solutions-oriented projects on energy development to identify how techno-ecological outcomes can be achieved simultaneously. Her background is also in plant and soil ecology of aridlands, where she and her students often uses these extreme environments to understand, predict, and respond to anthropogenic changes from local to global scales.

Beyond her research, Prof. Hernandez is a first-generation college graduate, graduate of the California community college system, and a proud first-generation Mexican American. Mexican Americans represent only 1.2 percent of faculty at baccalaureate-granting institutions in the United States; however, approximately two-thirds of Hispanics in the United States are Mexican American.

She lives in Granite Bay with her husband David, a United States Air Force veteran and commercial airline pilot, their two kiddos, and Primm their Parson Russell.

Postdoctoral Scholars

  • Uzma Ashraf, Ph.D.

    Alfred P. Sloan Postdoctoral Scholar

    Co-Mentors: Dr. Toni Lyn Morelli and Dr. Adam B. Smith

    Dr. Ashraf is an expert in species distribution modeling and a postdoctoral scholar funded by the Alfred P. Sloan Foundation in the Wild Energy Initiative. In this role, she studies the intersection between the conservation of wildlife and renewable energy development across the United States and identifying modalities of environmental justice in the planning process. Dr. Ashraf conducts research on wildlife conservation (e.g., snow leopards) and sustainability science (e.g., locust attacks, urban livability).

  • Elliott Steele

    Elliott Steele

    Postdoctoral Scholar | UC Wild Solar

    Dr. Steele is a postdoctoral scholar and restoration ecologist in the Wild Energy Center. He studies the relationship between wildlife and both ground-mounted and floating photovoltaics. The aim of his research is to determine how and why wildlife is impacted by solar panel infrastructures and ultimately, how potential negative impacts can be mitigated. Alongside restoration ecology, Dr. Steele's research spans animal behavior, field ecology, marine biology, and conservation science. He has studied a wide variety of animal taxa, including California mammals, birds, reptiles, amphibians, freshwater fish, pollinators, and tropical and temperate marine invertebrates. Elliott received his PhD from Dartmouth College where he studied the visual ecology of sociality. Prior to starting his PhD, Elliott was a conservation scientist at the San Francisco Zoo & Gardens where he raised endangered California amphibians and reptiles to be reintroduced into the wild.

Graduate Students

  • Moreen Akomea-Ampeh

    Ph.D. Student | Agricultural and Environmental Chemistry

    Co-Advised: Prof. Eliot A. Atakwama

    Moreen is a first year PhD student in the Agricultural and Environmental Chemistry Graduate Group at UC Davis. She graduated with a BA in Chemistry and a minor in Creative Writing at Augustana College, IL. Her research interest is in understanding whether there are perceived risks, particularly heavy metals, associated with emerging newer technologies: floating solar panels (FPVs). Eventually, she would want to extend the knowledge obtained from the FPV system to other systems impacted by heavy metals.
