Lewei Zhao, PhD


Lewei Zhao grew up in Xianyang, Shaanxi Province in China. He obtained his bachelor's degree in Hongyi Mathematics Honors Class from Wuhan University China in 2014. He went on to pursue a PhD from Wayne State University, Detroit, in 2019 in Applied and Computational Mathematics. He later joined Beaumont Proton Therapy Center from 2019 to 2023 as a Postdoctoral Scholar. During his postdoc, he completed the CAMPEP accredited medical physics certificate program offered at Wayne state University (2021-2022). His research interest is mathematical applications in medical physics.

Lewei joined the Stanford University Medical Physics Residency in 2023.
