Howard E. Epstein

Howard E. Epstein is the Sidman P. Poole Professor in the Department of Environmental Sciences at the University of Virginia, College of Arts and Sciences. He leads an active research group focused on ecosystem ecology, with field sites in the Arctic tundra of North America and Russia, as well as temperate forests in the U.S. Mid-Atlantic region. His work integrates field observations, remote sensing, and biogeochemical analysis to understand ecosystem responses to climate change.

• Ph.D., Colorado State University, 1997

Dr. Epstein's research centers on arctic vegetation dynamics, carbon cycling, and permafrost-vegetation interactions. He investigates how warming climates drive shrub expansion, ice-wedge degradation, and landscape transformation in tundra ecosystems. His work also explores carbon and water fluxes in temperate forest successional gradients. He employs advanced techniques including drone-based spectroscopy, satellite remote sensing, and flux tower measurements.

The recent publications highlight a strong focus on Arctic greening, permafrost degradation, and the use of remote sensing and machine learning to detect ecological change. His work spans spatial scales from fine-resolution drone imaging to continental-scale satellite analysis, with applications in climate modeling and ecosystem monitoring.

Dr. Epstein teaches core courses in ecology, including Terrestrial Ecology (EVSC 5220) and Fundamentals of Ecology (EVSC 3200). He advises graduate students and leads the Epstein Ecosystem Ecology Lab, which conducts fieldwork in diverse ecosystems from Alaska to Virginia. His research is supported by external funding, though specific grants are not listed in the provided text.

He has made significant contributions to understanding climate change impacts on high-latitude ecosystems, with publications in top journals such as Global Change Biology, Environmental Research Letters, and Nature Reviews Earth & Environment.
