Xiao Sun is a scientist at the Deutsches Elektronen-Synchrotron (DESY) and the University of Koblenz. She has more than seven years of experience in synchrotron-based characterization techniques and instrumentation. Her research focuses on (anomalous) small- and wide-angle X-ray scattering (SAXS/WAXS) for investigating the formation, growth mechanisms, and structure–property relationships of functional and catalytic nanomaterials. As a beamline scientist at the SAXSMAT beamline P62 at DESY, she contributed to the design, construction, and commissioning of the beamline. She is responsible for the development and operation of advanced sample-environment platforms, including microreactor systems and high-temperature catalytic setups for in situ and operando experiments. During her PhD at Forschungszentrum Jülich, she specialized in neutron scattering techniques, including neutron powder diffraction and small-angle neutron scattering (SANS), to study magnetic nanomaterials. Her work has been published in leading peer-reviewed journals, including Science and Nature Communications, as both author and co-author.
