Xingye Lu received his B. Sc. in Physics from Hebei University, China in 2008, and completed his Ph.D. in experimental condensed matter physics at the Institute of Physics, Chinese Academy of Sciences in July 2014. His work involves the use of neutron scattering to study the magnetic ordering and spin dynamics of iron-based superconductors, supervised by Prof. Pengcheng Dai. He visited Prof. Pengcheng Dai's group in Rice University from November 2014 to January 2015, prior to becoming a postdoctoral fellow (PSI fellow) working with Dr. Thorsten Schmitt at the Paul Scherrer Institut, Switzerland, where he focuses on measuring elementary excitations of correlated electron materials by means of resonant inelastic X-ray scattering.
