Timothy Chen

Timothy Chen is a physicist and scientist currently employed at Applied Materials since November 2022, where responsibilities include designing and constructing in situ laser and optical diagnostics for process chemistries in semiconductor manufacturing. Prior to this role, Timothy Chen served as a postdoctoral appointee at Sandia National Laboratories, focusing on the development of an optical centrifuge and techniques for measuring ro-vibrational temperatures in non-equilibrium molecular gases. As a PhD candidate at Princeton University from 2016 to 2021, Timothy Chen advanced laser diagnostics for methane reforming involving various measurement techniques, including time-resolved scattering and mid-infrared laser absorption. Timothy Chen obtained a Ph.D. in Mechanical Engineering from Princeton University and a Bachelor’s Degree in Mechanical Science and Engineering with a minor in Asian American Studies from the University of Illinois Urbana-Champaign.
