My research focuses on the evolution of technologies and on decomposing performance trajectories of energy systems. I am particularly interested in understanding the dynamics and limits of costs and carbon intensities of energy technologies, in order to inform climate change mitigation efforts. A subset of projects centers on nanostructured energy technologies and their potential to reach very low costs and carbon intensities. I received my B.S. in materials science and engineering from Cornell University and my Ph.D. in materials science from the University of Oxford, where I studied as a Rhodes Scholar. I have also worked for the United Nations, and as an advisor to the private sector on investment in low-carbon energy technologies.
