Luke Theogarajan is interested in energy-efficient circuit architectures for computation and energy efficient materials for light-harvesting. He is currently collaborating with Institute Director John Bowers to design an energy-efficient electronic-photonic interconnect for multiprocessor communication. Theogarajan concurrently is working on novel light-harvesting polymers for a low-cost solution to designing luminescent solar concentrators (LSCs). LSCs offer a way to effectively couple highly efficient inorganic solar cells with organic dyes, lowering the cost.
