Alex J. Welch
Alumni Resnick Graduate Research Fellow
Alex graduated from Caltech with a PhD in applied physics and conducted 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 focused on electrochemically transforming CO2 into useful chemicals and imaging the local environment in gas diffusion electrodes for CO2 reduction. These images 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.
Alex is currently an engineer at CarbonCapture Inc.
