Howard Epstein

Howard Epstein is a Professor in the Department of Environmental Sciences at the University of Virginia, where he has served since 1998. He co-directs the second-year College Science Scholars program and teaches core courses including Fundamentals of Ecology, Terrestrial Ecology, and Ecology of Grasslands and Tundra.

Education:

• Ph.D. in Ecology, Colorado State University (1997)

Research Focus: Professor Epstein specializes in Arctic tundra ecosystems, investigating vegetation dynamics (greening/browning events), permafrost interactions, and climate change impacts. His work integrates field studies with advanced remote sensing and machine learning to produce high-resolution vegetation maps across circumpolar regions. He also examines ecological processes in temperate grasslands and shrublands, particularly secondary succession and nutrient cycling in Virginia's Ridge and Valley.

Publication Trends: Recent work emphasizes machine learning applications for tracking shrub expansion at unprecedented resolutions, alongside studies of hydrological changes in Arctic communities like Utqiaġvik. His research increasingly connects built environments with natural ecosystems while addressing permafrost degradation consequences through geophysical methods.

Academic Contributions: Beyond teaching, Professor Epstein contributes to major scientific assessments including the NOAA Arctic Report Card, where he authors sections on tundra greenness. His leadership in the College Science Scholars program demonstrates commitment to undergraduate mentorship in ecological sciences.
