Matt Sieger is the Deputy Project Director for the Oak Ridge Leadership Computing Facility (OLCF).

Matt received a B.S. in Physics from the University of Missouri at Rolla (now Missouri S&T), and his M.S. and Ph.D. in Physics from the University of Illinois at Urbana-Champaign. He then moved to Pacific Northwest National Laboratory as a postdoctoral researcher and later as a member of the scientific staff, where he led a dual experimental and theoretical effort to understand the physics of electron-stimulated chemistry at surfaces, including those of icy solar system bodies. Matt was the recipient of the 1998 Outstanding Postdoc award at PNNL’s Environmental and Molecular Sciences Laboratory. He has authored or co-authored more than 30 articles in the peer-reviewed literature.

In 2000 Matt joined Intel Corporation in Portland, Oregon, as a senior engineer in process technology development, where he helped transfer Intel’s first copper interconnect process technology from the lab to high-volume manufacturing. Later he led a computational quality and reliability effort which developed comprehensive statistical models of processors, chipsets, and integrated systems including power, thermal and reliability characteristics, used by Intel to simulate and optimize the entire product life-cycle from manufacturing, sort and class test binning to end use.

After a short stint as the Chief Software Architect for a Knoxville-based startup, Matt joined ORNL in 2009 as a Quality Manager, where he worked with the Consortium for the Advanced Simulation of Light Water Reactors (CASL), the Nuclear Science and Engineering Directorate, and the Spallation Neutron Source. He has made contributions to a number of projects across the laboratory in quality and project management, software QA, business process improvement, assessments, operations management, and IP licensing and export control.
