Angela Feldhaus took a leave of absence from her Ph.D. program in Applied Mathematics at Harvard University to co-found Rarefied Technologies. Her research on photophoretic levitation led to the co-development of Rarefied’s  core technology. With a background in physics, applied mathematics, and economics, she is a co-inventor on the patent-pending technology and has over 10 years of nanofabrication experience, including at Sandia National Labs. Angela is a former NSF Graduate Research Fellow, Clarendon Fellow, St Gallen Symposium winner, and NSF I-Corps technical lead. In 2022, she was awarded a fellowship to study innovation and entrepreneurship at Harvard Business School.
