Curriculum Vitae


Dr. Abby Frazier is a climatologist who studies the spatiotemporal dynamics and impacts of climate change and climate variability. Her research uses geospatial analysis to integrate diverse datasets, including models and observations, to understand the mutli-disciplinary impacts of climate on freshwater resources and ecosystems over regional and global scales, with a focus on Pacific Islands. She is interested in climate extremes, particularly the impacts of drought and the El Niño-Southern Oscillation on local hydrology and wildfire regimes. She collaborates closely with stakeholders to co-produce actionable science to support climate change decision making and natural resource management.

Before joining Clark University, Dr. Frazier was a Research Fellow at the East-West Center in Honolulu, HI (2018-2021), and a postdoctoral Research Geographer at the USDA Forest Service Institute of Pacific Islands Forestry (2016-2018). She earned her Ph.D. and M.A. degrees in geography from the University of Hawai‘i at Mānoa and has a B.A. in geography and a B.S. in mathematics from the University of Vermont.
