We research and develop higher-performance and lower-cost materials and devices for energy generation, storage and conversion. Our target industries are electric vehicles, microgrids, photovoltaic panels, wind turbines, wearable power devices, and more.

UC San Diego's world-renowned microgrid serves as a real-world test-bed for our work, which is rooted in thoughtful analyses of the economics of distributed energy.

At every point along the way, we train and mentor our students to become tomorrow’s workforce for green and advanced energy.
