My scientific work
My passion is using data science as a multi-disciplinary tool to empower communities to sustainably shape their environments.
During my PhD at the University of Illinois at Urbana-Champaign, I studied the impact that green infrastructure has on urban resilience. I leveraged a multi-disciplinary framework to look at resilience from a technical, socio-economic, and legal framework. My work led to the creation of a webtool and graphical interface that communities can use to determine appropriate green infrastructure design for their native soils and landscapes.
As a AAAS Science, Technology, and Policy Fellow with the U.S. Department of Energy, I managed projects that decarbonized the water and wastewater sectors. I was also part of an interagency task-force led out of the White House that aimed to improve the climate resilience of federal infrastructure projects.
In my current role with Isle Utilities, I manage a diverse portfolio of projects at the intersection of water, energy, and the environment, with clients spanning academia, industry, utilities, and the federal government. In particular, my work with Isle's Trial Reservoir helps to mitigate risk for utilities seeking to pilot innovative new technologies in low income and minority communities.
