Short presentation
As associate professor in Solar Cell Technology, I divide my time between teaching Masters courses in solar energy and leading research on next-generation optoelectronic materials. My research centers on exploration of robust, abundant materials that could enhance solar cell performance and lifetime while reducing costs. The experimental materials science is supported by first principles theory and, increasingly, automation of physical and analytical processes for better, faster data generation.
