Alumni - Industry and Private Sector
Alex defended on October 1st, 2021. She graduated from Stanford University in 2016 with a BS in Engineering Physics. Her previous research focused on using plasmonic hot carriers to create a photon upconverter. In the Atwater group, she was part of JCAP (Joint Center for Artificial Photosynthesis) and LiSA (Liquid for Sunlight Alliance), and she was supported by the NSF Graduate Research fellowship. When she is not doing science, Alex is likely to be running or hanging out with friends.
