Xiaoran Roger Liu is a Ph.D. candidate in Department of Chemistry, Washington University in St. Louis (Missouri, U.S.). He received his B.E. in Applied Chemistry from East China University of Science and Technology (Shanghai, China), where he focused on the synthesis and characterization of novel hyperbranched surfactants. He then moved to the College of Polymer Science and Polymer Engineering, The University of Akron (Ohio, U.S.). During his M.S. work with Dr. Toshikazu Miyoshi, he focused on structural characterization of carbon fiber precursors during thermal stabilization by solid-state nuclear magnetic resonance. His Ph.D. work with Dr. Michael L. Gross now focuses on understanding protein higher order structures through developing and applying novel mass spectrometry-based approaches, most notably: fast photochemical oxidation of proteins, hydrogen deuterium exchange, footprinting by targeted reagents, and native spray. He has authored and coauthored over 10 publications, delivered oral and poster presentations for various conferences, and served as a peer reviewer for many journals. His scientific contributions and community engagements have been recognized with numerous awards, most recently the Lake Louise Marg Northcott Award by Canadian Society for Mass Spectrometry.
