Dr. Gerald Miller, professor and associate director in the School of Civil Engineering and Environmental Science at the University of Oklahoma, is a member of the OK NSF EPSCoR Track-1 RII Award titled Socially Sustainable Solutions for Water, Carbon, and Infrastructure Resilience in Oklahoma. The $20 million research project is a social science-led, multi-disciplinary collaboration among social, physical, biological, engineering, and computational scientists. More than thirty researchers from across the state are working together on the project, which began July 1, 2020.

Dr. Miller's research in the areas of civil engineering and geotechnical engineering supports the OK NSF EPSCoR project's Focus Area 4: Sustainable Water and Energy Infrastructure (SI). The SI focus area's primary goal is to develop an aggregated resilience model to characterize the influence of diverse stakeholders’ decision-making behavior on the functions of interdependent infrastructure systems. Through the development of this model, the SI focus area will advance understanding of the ways in which Oklahoma’s interdependent water and energy infrastructures interact with severe weather, S2S extremes (pluvial events and droughts), carbon cycle patterns (changing land use and increased frequency and scope of wildfires), and water management/reuse patterns (both surface and subsurface, requiring siting and sizing including increases in storage and pipeline capacities). This understanding will facilitate the development of an array of solution options for enhancing the state's infrastructure resilience that span the project focus areas (weather, water, and carbon/land use), enabling socially sustainable solutions.
