Water-Climate-Society: Assessing Risk in a Changing Hydrological Landscape

The First Virginia Climate Assessment

Welcome!

I study the changing hydrological cycle, with a focus on hydroclimatic extremes such as hurricanes and flooding, their drivers, and associated societal risks. By combining Earth system modeling and probabilistic approaches with multi-source datasets, my work enhances the predictability of compound extreme events and evaluates their long-term shifts.

Particularly,
1) I study extreme precipitation trends and patterns from regional to continental scales using multi-source datasets, e.g., satellite estimates, in-situ observations, and global climate models.

2) I study how anthropogenic climate change influences the intensity and frequency of the rarest rainfall events from tropical storms using probabilistic and Earth system modeling approaches.

3) I evaluate the performance and accuracy of rainfall products. In what ways do the distinct underlying frameworks—specifically satellite retrieval structures, reanalysis physical assumptions, and ensemble algorithms—affect the accuracy of gridded precipitation products in complex terrains?
