Edward Sargent’s research in environmental engineering focuses on energy and fuels.

Specifically, he investigates the use of colloidal quantum dots to improve device performance and reduce manufacturing costs. By tuning the size and properties of these semiconductor nanoparticles, photovoltaics can capture more of the sun’s energy. Also, infrared security cameras can be manufactured on a large scale, rather than using current manual assembly methods. Sargent’s research team is also interested in how nanomaterials can be used to sense the presence of disease indicators, and transform these signals into diagnostic devices.
