J. “Robert” Michael, PhD, is Chief Data Architect for the National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory (ORNL). In this role, Dr. Michael supports the development, refinement, and architecture of strategies to overcome challenges encountered in data-intensive computing across many NCCS programs. Along with identifying cutting edge and innovate solutions to the NCCS’s data science challenges, he acts as a customer facing subject matter expert in the areas of data engineering, data architecture, and resource utilization to ensure that NCCS resources are being efficiently utilized to support a wide range of scientific applications and systems, including those in the protected data space. Dr. Michael also serves as the Acting Director of CADES.

Prior to joining ORNL, Dr. Michael spent more than five years at St. Jude Children’s Research Hospital in various roles including High Performance Computing (HPC) Specialist, Sr. Software Engineer, and Manager of Bioinformatics Software Development and Operations. During his tenure at St. Jude, he solved a variety of technical challenges related to HPC scheduling of I/O intensive workloads, designed and implemented user education seminars and outreach programs, and led the design of software and hardware infrastructure to support large scale automated Bioinformatics pipelines for hybrid HPC / Cloud computing environments.

Dr. Michael received a BS in Mathematics, MS in Mathematics, MS in Computer Science, and PhD in Computational Science with an emphasis in Physics, focusing on the mathematical modeling of the dynamic electron density via computational simulations. During his graduate work, he taught Math at the undergraduate level for several years and currently enjoys spending time with his wife and two children when he is not at work.
