Dr. Dupigny-Giroux is a Professor of Climatology in the Department of Geography and Geosciences, the Vermont State Climatologist since 1997, and the President of the American Association of State Climatologists from 2020-2022. In 2020, she was appointed by the Vermont House of Representatives to the Vermont Climate Council as the member with expertise in climate change science.

Dr. Dupigny-Giroux teaches introductory and intermediate-level courses in climatology, physical geography and remote sensing. Her advanced level capstone seminars delve into Climatology and Natural Hazards, as well as Satellite Climatology and Land-Surfaces Processes. Many of her courses are Service-Learning collaborations with municipalities across the state, State of Vermont Agencies, and Federal entities such as NOAA. 

She holds a B.Sc. in Physical Geography and Development Studies from the University of Toronto (1989), an M.Sc.(1992) in Climatology and Hydrology and a Ph.D. (1996) in Climatology and Geographic Information Systems from McGill University.

An applied climatologist by training, Dr. Dupigny-Giroux's research interests intersect a number of interdisciplinary fields including hydroclimatic natural hazards and climate literacy, climate services, geospatial climate and land-surface processes, all within the context of our changing climate. She is an expert in floods, droughts and severe weather and the ways in which these affect the landscape and peoples of Vermont and the US Northeast. She has worked extensively with K-12 teachers and students, bringing the use of satellites, climatology and climate change to all levels of the pre-university curriculum. She is the lead editor of Historical Climate Variability and Impacts in North America, the first monograph to deal with the use of documentary and other ancillary records for analyzing climate variability and change in the North American context.

A Fellow of the American Meteorological Society, Dr. Dupigny-Giroux is currently serving three-year terms on three committees/boards of the National Academies of Science, Engineering and Medicine, including the Board of Atmospheric Sciences and Climate. She was invited by the White House Office of Science and Technology Policy Program (OSTP) to be a presenter on the "Climate Science Leading the Way" panel at the COP26 meeting in Glasgow, Scotland in 2021. She has contributed to all five National Climate Assessments, serving as the lead author for the Northeast Chapter of the 2018 Fourth National Climate Assessment of the US Global Change Research Program, and is an author on the national water chapter of the Fifth National Climate Assessment.
