Atwater Research Group

Illuminating the intersection of nanophotonics and energy

We are on a mission to advance matters related to diversity, equity and inclusion (DEI), aspects that are essential and foundational to advancing knowledge in science and engineering. Our research is focused on light matter interactions at the nanoscale and energy conversion, encompassing quantum nanophotonics, metasurfaces, two-dimensional and layered materials, solar photovoltaics and photoelectrochemical energy conversion.
