Gabe developed his skills in bee and bark beetle taxonomy while conducting his master’s thesis and post-graduate research at Oregon State University.
Zack Steel, PhD | Postdoctoral Researcher | email@example.com
Zack is a postdoctoral researcher at UCD and Berkeley. Through his research he seeks to improve our understanding of how acute (e.g. wildfire & drought) and chronic (e.g. climate) environmental stressors structure ecological communities, how landscape pattern mediates environmental drivers, and how anthropogenic change at local to global scales directly or indirectly alters community dynamics and species distributions. His post-doctoral research assesses impacts of extreme drought on Sierran conifer forests, informs reforestation prioritization within areas of high tree mortality, and investigates the ecological consequences and patterns of managed wildfire in Yosemite and Kings Canyon National Parks. His dissertation research focused on how wildfire and forest management alters landscape pattern, and influences habitat use of birds and bats in the forests of California’s Sierra Nevada Mountains.
Carrie Levine, PhD | Postdoctoral Scholar | firstname.lastname@example.org
Carrie Levine is a forest ecologist whose research is based in the Sierra Nevada mixed-conifer forests of California. Over the last century, these forests have experienced altered fire regimes, timber harvesting, a warming climate, chronic air pollution, and uncharacteristically severe attacks by pests and pathogens, resulting in a shift towards a low-diversity forest system. Carrie works across temporal scales to incorporate historical and contemporary datasets into models that can help predict future ecological conditions under changing climate regimes. Carrie’s research is focused on applying concepts of ecological resilience in management, restoration, and conservation contexts in order to bridge the gap between theory and practice. In 2017, Carrie completed her PhD at the University of California, Berkeley in the Department of Environmental Science, Policy, and Management and is now a postdoctoral scholar in the Safford Lab.
