Congrats to our new fellows Zachary Lee and Kyle Virgil!
Zach is developing an open-source toolbox for EV charging research based on data and insights captured from charging systems in use today. He is advised by Professor Steven Low and is part of Low’s team that helped develop the software and algorithms that make up the Adaptive Charging Network (ACN), a framework for smart charging systems, which was developed at Caltech and has since been commercialized by PowerFlex, a Caltech startup.
Kyle researches new materials for enhanced or “next-generation” photovoltaics, including hybrid perovskites. He aims to understand the charged particle movement within these materials towards the development of cheaper, more robust and globally accessible solar energy technology. Kyle is advised by Professors Geoffrey Blake and Harry Atwater.

The apparatus Giapis designed to perform the reaction works like a particle accelerator, turning the CO2 molecules into ions by giving them a charge and then accelerating them using an electric field, albeit at much lower energies than are found in a particle accelerator.
He hopes that a variation of his reactor could be used to do the same thing at more useful scales—perhaps one day serving as a source of breathable air for astronauts on Mars or being used to combat climate change by pulling CO2, a greenhouse gas, out of Earth's atmosphere and turning it into oxygen.
