Laurie Stephey Ph.D.
Postdoctoral Fellow
NERSC

Background

Laurie Stephey is a postdoc at NERSC in the NESAP for Data program. She will be working with the DESI (Dark energy spectroscopic instrument) project to help make their large-scale data processing run efficiently on the NERSC Cori KNL-based system. 

Laurie earned her Ph.D. from the University of Wisconsin-Madison in 2017 studying edge physics in the HSX and W7-X stellarators. In 2009, she earned her B.A. in Physics from Rollins College in Orlando, Florida. She has also worked on musical acoustics, thin-layer deposition, and memristor device research projects.
