Qun Shen

Deputy Director for Science, NSLS-II

Dr. Shen is the Science Director of the National Synchrotron Light Source II (NSLS-II), and a Senior Physicist at Brookhaven National Laboratory. He oversees the development and strategic planning of the scientific programs at NSLS-II, including interactions with the broad scientific user community and the development of high-level user access policies and processes. During the construction phase of the NSLS-II, Dr. Shen served as the Experimental Facilities Director and a member of the executive leadership team, and was responsible for development of all aspects of experimental programs in the NSLS-II Project.

Before joining Brookhaven in 2008, Dr. Shen was Head of the X-ray Microscopy and Imaging Group at the X-ray Science Division at the Advanced Photon Source in Argonne National Laboratory. He also held Adjunct Professorships in Materials Science & Engineering at Northwestern University and in Physics at Purdue University. Prior to Argonne, he was a Senior Staff Scientist and Head of the X-ray Optics Group at Cornell High Energy Synchrotron Source, and an Adjunct Associate Professor in Materials Science & Engineering at Cornell University for more than seventeen years. He held visiting scholarship and professorships at the European Synchrotron Radiation Facility in France and at the Chinese Academy of Sciences in China.

Dr. Shen is the recipient of numerous professional awards during his career, including the first CUSPEA '81 Fellowship for graduate studies in the US. He is an elected Fellow of the American Physical Society for important contributions to x-ray physics, particularly in the field of x-ray diffraction in relationship to the phase problem in proteins. He has received the Distinguished Alumnus Award from the School of Science at Purdue University, the S.S. Sidhu Award on outstanding contributions in the area of x-ray diffraction and scattering from the Pittsburgh Diffraction Society, and the Lark-Horowitz Prize in Physics from Purdue University. Dr. Shen was a Scientific Member and Developer during the early stages of the Synchrotron Radiation Instrumentation Collaborative Access Team at the APS, with the particular emphasis on x-ray physics of materials and polarization studies.

In addition to overseeing and managing the NSLS-II science programs, Dr. Shen’s current research interest focuses on high-resolution x-ray microscopic studies of nanoparticles, heterogeneous noncrystalline specimens, and biological cells and assemblies using both lens-based x-ray microscopes and lensless imaging methods based on coherent diffraction and phase retrieval as well as their applications.
