Assistant Professor; Faculty Director of Impact and Innovation, GW Alliance for a Sustainable Future


Professor Caitlin Grady studies the form and functions of interconnected infrastructure across water, food, and energy systems. Her research seeks to combine network models, socio-technical data, and ethical-epistemic analyses to create a more sustainable and secure environment. Current projects include modeling embedded nitrogen trade and its influence on water quality, climate change impacts on hydropower and the U.S. electricity grid, ethical implications of research choice in spatial science, and managing critical infrastructure under uncertainty. Her work is currently supported by the National Science Foundation and the U.S. Department of Agriculture.
