Deborah Sunter

Deborah Sunter received a B.S in Mechan­i­cal and Aero­space Engi­neer­ing at Cor­nell University. There she developed a nanosatel­lite mis­sion that was suc­cess­fully launched into orbit. Although fas­ci­nated by aero­space applica­tions, the time- critical issue of global warm­ing shifted her focus in grad­u­ate school to explore renew­able energy. Spe­cial­iz­ing in com­pu­ta­tional mod­el­ing of thermo-physics in mul­ti­phase […]

Wolfgang Habla

Wolfgang works at the intersection of political economy and environmental economics. His current research focuses on how national politics form international policies; on the political economy of environmental tax reforms, and on the strategic interaction of governments facing mobile factors of production such as capital and energy.

Rebecca R. Hernandez

University of California President's Postdoctoral Fellow

Rebecca's work examines processes where human and natural systems interact and those that elucidate the functioning of the Earth system. Her research quantifies and informs a broad range of topics from global environmental change to renewable energy systems.
