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 helps provide and support Python for over 3000 users. She serves as a project liaison for the KSTAR and DESI superfacility teams. She is also interested in containers, scientific workflows, and NERSC center data analysis.

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.

Research Interests

Using Python in scientific computing, GPU Python data analysis with Dask/RAPIDS, container infrastructure, plasma physics and fusion, astronomy/cosmology
