Justin M. Wozniak

Computer Scientist 3

Wozniak researches and develops workflow systems for high performance computing.

Biography

Justin Wozniak joined the Mathematics and Computer Science Division at Argonne National Laboratory in spring 2008 and the staff of the Computation Institute at the University of Chicago in Winter 2009.  He became a Fellow at the University of Chicago in 2014, and transferred to the new Data Science and Learning Division at ANL in 2018.

He has designed and implemented novel workflows systems for scientific applications, combining techniques from high-performance computing, grid computing, and Internet computing. To gain insight into next-generation computing systems, he has developed simulators to study the effects of policy changes in large-scale system software such as schedulers and storage management algorithms. Additionally, he collaborates with the many-task computing community to support the rapid development of scalable applications and provide portable, efficient access to the largest computing installations.
