Michael Ernst

Michael Ernst received his Ph.D. in computational science from Technical University Berlin in 1983. He is currently a staff member of the Physics Department and the director of the RHIC and ATLAS Computing Facility (RACF) at Brookhaven National Laboratory. In his career of 35 years Dr. Ernst has made major contribution to the evolution of computing services in high energy and nuclear physics. Particular areas include coordination of international networking in Europe, and designing and implementing distributed, grid-enabled storage solutions that became foundational elements in LHC computing He has worked at Deutsches Elektronen Synchrotron (DESY) in Germany, CERN in Switzerland, and Fermi National Accelerator Laboratory (Fermilab) near Chicago. During his nearly 25 years at DESY, he was Director of Computing between 1997 and 2002, followed by a two-year stay as a visiting scientist at Fermilab, where he headed the development of the US CMS Tier-1 center. When DESY joined the CMS collaboration he became co-coordinator of the CMS computing integration program. In 2007 Dr. Ernst accepted a position as Director of the RHIC and ATLAS Computing Facility at BNL and he is the U.S ATLAS Facilities Manager with responsibilities for the US ATLAS Tier-1 center, the largest of 10 ATLAS Tier-1 centers worldwide, and five Tier-2 centers at 9 universities and one National Laboratory (SLAC) in the U.S.

Dr. Ernst is a member of the Open Science Grid Executive Team that is steering the activities of a vital piece of national High Throughput Computing (HTC) infrastructure serving the computational needs of a broad variety of science domains. He is serving on several national and international committees providing advice on the evolution of computing to funding agencies, scientific programs and national data centers around the world. He is advising and representing the Worldwide LHC Computing Grid and the ATLAS experiment on topics associated with high-performance Wide Area Networking.
In 2010 Dr. Ernst received the Brookhaven Science and Technology award and in 2011 he and the RACF group received the Secretary of Energy Service Achievement Award. 

Research Interests

  • Using high-performance networking to incorporate remote compute and information resources into local computational environments
  • Management and scheduling techniques that empower high throughput computing on local and wide area clusters of distributively owned resources
  • Tools for efficient access and storage management of massive scientific data sets
