Brian Coyne
Advanced Lecturer, Political Science
BioBrian Coyne is an Advanced Lecturer in Political Science and serves as the Nehal and Jenny Fan Raj Lecturer in Undergraduate Teaching. He received his B.A. in Government from Harvard College in 2007 and his Ph.D. in Political Science from Stanford University in 2014. His dissertation, "Non-state Power and Non-state Legitimacy," investigates how powerful non-state actors like NGOs, corporations, and international institutions can be held democratically accountable to the people whose lives they influence. Coyne's other research interests include political representation, responses to climate change, and the politics of urban space and planning. In addition to Political Science, he also teaches in Stanford's Public Policy, Urban Studies, and COLLEGE programs.

Dylan Marshall Crain
Ph.D. Student in Energy Resources Engineering, admitted Autumn 2022
Current Research and Scholarly InterestsMy current research revolves around optimizing the monitoring design of Carbon Capture and Sequestration (CCS) projects in such a way that the posterior (after data assimilation) predictions are as close to reality as can be hoped for.
In CCS projects within the U.S., it is important to have monitoring plan, which can consist of wells with pressure, saturation, salinity, et cetera sensors, seismic lines, or gravimetric above-ground measurements, before any injection has begun into the subsurface. This is due to the permitting requirements that must be satisfied before operations are begun.
Due to this constraint, any monitoring optimization (at least initially) needs to be determined using only a prior (highly uncertain) understanding of the subsurface. This makes the optimization much more challenging. We utilize a prior optimization scheme from a previous student which allows us to optimize a monitoring plan using only prior information to get the minimized, expected uncertainty reduction in the posterior models for a given quantity of interest. This scheme is limited by some Gaussian assumptions. We optimize it using a genetic algorithm.
From this point, with the monitoring plan established, the information gathered from the optimized monitoring scheme (using only monitoring wells at the moment) is used to history match (data assimilate) our understanding of the subsurface. The results can be used to predict the CO2 plume flow and behavior into the future.
This work was initially developed to assist a project in Illinois that is currently seeking Class VI injection well permits in the self-same state in order to begin injecting CO2 produced from two companies paying for the work from the Illinois Geological Survey.
