Hi! I’m Claire Halloran (they/them), a geospatially-focused energy system modeler specialized in power-to-X/sector-coupling applications and electricity demand changes. As a doctoral candidate in energy systems engineering at the University of Oxford Energy and Power Group funded by the Rhodes Scholarship, I incorporate spatially granular heating data into electricity system planning models to assess the impact that residential heat pump deployment will have on the electricity system. As a part-time research assistant in the Climate Compatible Growth program, I developed an open-source geospatial planning tool to optimize green hydrogen production and transport. I’m also a bit of a map nerd and enjoy communicating with policymakers and general audiences about my research. Before starting my PhD, I earned my Bachelor’s in Materials Science and Engineering at MIT.
