Dr. Ke An received his M.S. from Department of Chemical Engineering, Tianjin University, and Ph.D. from Department of Engineering Science and Mechanics, Virginia Tech. He is the Senior and Lead Scientist of the versatile materials science and engineering diffractometer, the VULCAN beamline, at the world most intense pulsed neutron source Spallation Neutron Source (SNS), funded by Basic Energy of Science, Office of Science, Department of Energy. He also holds an Adjunct Associate Professor position at the Department of Materials Science, the University of Tennessee, Knoxville. Since 2017 he has started leading the Materials and Engineering Initiative of Neutron Science Directorate to promote neutron science in area of M&E. Starting in 2016, he leads the newly formed Industrial Application Program of SNS and HFIR to promote the engagement of industrial users in using neutrons. Since 2007, he has been a major team member of the design and construction of the VULCAN instrument. He leads in commissioning, operation and further upgrade of the VULCAN beamline. The VULCAN beamline started commissioning in 2009 and entered successfully the general user program in 2010. Since then, he and the instrument team have grown a vibrant user program in materials research with neutron diffraction in energy storage and conversion materials (batteries and fuel cells materials), engineering structural materials, and functional materials, etc.
