Alex Welch

Graduate Student

626-395-2821



Alex is a graduate student in Material Science and joined the Atwater group in September 2016.  She graduated from Stanford University in 2016with a BS in Engineering Physics.  Her previous research focused on using plasmonic hot carriers to create a photon upconverter.  In the Atwater group she will be a part of JCAP (Joint Center for Artificial Photosynthesis), and she is supported by the NSF Graduate Research fellowship.  When she is not doing science, Alex is likely to be running or hanging out with friends.
