Welcome
Chang-Chun Chen 陳昶君
Postdoctoral Research Associate — Los Alamos National Laboratory
Postdoctoral Research Associate — Los Alamos National Laboratory
Chang-Chun "Samantha" Chen, a Postdoc Research Associate at Los Alamos National Laboratory since August 2022, specializes in building theoretical models and analyzing momentum and energy transport in Hydrodynamics and Magnetohydrodynamics (MHD). Her impactful research addresses the pure fluid and MHD turbulence, contributing to our understanding of fundamental physics related to transport and particle acceleration in the fusion plasma physics and in the universe.
During her time at UCSD, mentored by Patrick Diamond, she delved into angular momentum transport and MHD instabilities. Ms. Chen's research interests span fluid dynamics, fusion plasma physics, and plasma astrophysics, with a notable project on β-plane MHD turbulence in the Solar tachocline. With an undergraduate degree in physics from National Tsing Hua University (Taiwan), she also contributed to the Atacama Large Millimeter/submillimeter Array program, developing skills in observational radio astronomy.
