I was a Ph.D. student in the Electrical Engineering and Computer Sciences department at the University of California, Berkeley, advised by Professor Ali Javey. My research interests were in the areas of semiconductor devices, solar cells, and solar fuel generation. I worked on inventing new low-cost manufacturing techniques to produce high efficiency solar cells, and then analyzing the potential cost and feasibility of those techniques at industrial scale.
