Melanie Kirkham is the Scientific Associate for the Powgen powder diffraction beamline (BL-11A) at the Spallation Neutron Source (SNS). Prior to joining the Powgen team in 2012, she was a postdoc in the Materials Science and Technology Division at ORNL, working with Andrew Payzant and Edgar Lara-Curzio on phase transitions in thermoelectric materials, as well as providing user support in X-ray diffraction (XRD) for the High Temperature Materials Laboratory (HTML). Melanie earned her Ph.D. in Materials Science and Engineering (MSE) from the Georgia Institute of Technology, where she worked with Bob Snyder and Z.L. Wang studying one-dimensional nanostructures using XRD and electron microscopy. Melanie earned her M.S. and B.S. in MSE from the University of Tennessee, Knoxville, working with Claudia Rawn on hexacelsian.
