Laurie Stephey is a Scientific Data Architect in the Data Analytics and Services group. Previously she was a postdoctoral fellow in the NERSC NESAP for Data program. She works on NERSC's container infrastructure and Python teams, she serves as a project liaison for the DIII-D and KSTAR fusion science teams, and she is also interested in scientific workflows and NERSC center data analysis.
Laurie earned her Ph.D. from the University of Wisconsin-Madison in 2017 in magnetic confinement fusion 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.
