Andrew W. Ellis

Associate Professor

Specialities:

·     Climate science, meteorology

·     Hydroclimatic variability and change, snow, drought, water supply

·     Synoptic climatology

I am a native of Delaware and earned Bachelor of Arts (Geography, 1991), Master of Science (Geography, 1994), and Doctor of Philosophy (Climatology, 1997) degrees from the Geography program at the University of Delaware in Newark, Delaware.  In 1997, I joined the geography faculty at Arizona State University in Tempe, Arizona where I remained until leaving for Virginia Tech in July 2011. A hydroclimate scientist, my early research work focused on snowfall variability, snow cover-atmosphere interactions, and snow melt modeling. However, I spent several years working on lower atmospheric pollution problems before returning in recent years to a research agenda focused on water-related issues. Two research areas have been the focus of my most recent work. One area centers on understanding the occurrence of drought and its improved representation for monitoring and study. The second research area focuses on assessing the sustainability of fresh water resources for populations living in arid and semi-arid climates given population growth and the uncertain hydrological impacts of climate change.
