Alex J. Welch
Resnick Graduate Research Fellow
Alex is a graduate student in applied physics conducting research at the Joint Center for Artificial Photosynthesis with Prof. Harry Atwater. She earned a BS degree in engineering physics from Stanford University in 2016. At Stanford, she became interested solar energy conversion and conducted research on transparent conductive materials and photon upconversion with Yi Cui and Jennifer Dionne respectively. At Caltech, her research has focused on electrochemically transforming CO2 into useful chemicals. In her current work, she plans to image the local environment in gas diffusion electrodes for CO2 reduction. These images will reveal new information about the water layer in these promising, but not well understood devices, as well as the local pH. Alex's passion for sustainability comes from her love of exploring the outside world – scuba diving, hiking, camping, sailing, and skiing.
