Biographical Sketch

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 team, the NERSC Workflows working group, and she serves as a project liaison for the DIII-D fusion science teams.

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.

Research Interests

Making containers ubiquitous in HPC, enabling real-time scientific workflows, Dask, workflow tools, leveraging Python in scientific computing, plasma physics and fusion, astronomy/cosmology
