Justin Wozniak joined Argonne as a postdoc in 2008 and has been a member of the Data Science and Learning Division since its founding in 2018.  He has had a joint appointment at the University of Chicago since 2009, and is currently a Scientist-at-Large.

Wozniak designs and implements workflow systems for scientific applications and deep learning workloads, combining techniques from high-performance computing and distributed computing.  He has extensive experience integrating advanced computing techniques in collaboration with the experimental and simulation sciences.
