Each year the College of the Environment provides faculty-student research grants to provide faculty and their students an opportunity to conduct research that would not have been otherwise possible. Helen Poulos, adjunct assistant professor of environmental studies, and environmental studies & earth and environmental sciences major Ally Detre ‘22 launched a faculty-student research collaboration during the 2020-21 academic year working on a dataset documenting native woody plant recovery in the Big Bend Region of the Rio Grande. Ally received a COE summer fellowship in 2021 that allowed her to gain first-hand knowledge of the area with a trip to Big Bend National Park to resurvey a stretch of the river that experienced recent native riparian plant recovery and to work as a GIS technician for the Science and Resources Management division of Big Bend National Park.

poulos receives $300k nasa research grant
Dr. Helen Poulos, adjunct assistant professor of environmental studies, has been awarded a $300,000 NASA grant to examine forest type-conversion through the lens of evapotranspiration (plant sweat) in response to high-severity wildfire in southeastern Arizona. Poulos and her team will conduct their research using imagery gathered by the ECOSTRESS sensor mounted on the International Space Station. It will be the first-ever test of the ECOSTRESS sensor’s applicability for wildfire-related research.
Plants facing the aftermath of wildfire often have insufficient water, which causes their temperature to rise. The ECOSTRESS radiometer measures the temperatures of plants across Earth to an extraordinarily accurate degree. Poulos’s NASA-funded project will specifically investigate the effects of the 2011 Horseshoe Two Fire on post-fire plant and site water balance and evaluate the potential of using data gathered from the ECOSTRESS sensor to predict wildfire effects on plant community structure and water relations in an Arizona Sky Island pine-oak forest.
poulos researches fire effects in arizona
Adjunct Assistant Professor of Environmental Studies Helen Poulos traveled to Arizona in March 2019 to research fire effects of the 2018 Pinery Canyon Fire on agaves in the Chiricahua Mountains. Poulos is working on the project in collaboration with Wes astronomy major Hunter Vannier ‘20.
While in the Grand Canyon State, Poulos also spent time researching the effects of the 2017 Frye Fire on mixed conifer forests of the Pinaleño Mountains, a project in collaboration with Dr. Don Falk at University of Arizona.
