MA Xiaoguang
Assistant Professor

Brief Introduction
Xiaoguang Ma is Assistant Professor at Center for Complex Flows and Soft Matter Research and Department of Physics. He obtained his bachelor's and master's degree from Sun Yat-Sen University. After receiving his Ph.D. in physics from the Hong Kong University of Science & Technology, he was appointed LRSM-Solvay Fellow at University of Pennsylvania, focusing on soft matters and complex fluids. He was also an investigator at Solvay's Complex Assemblies of Soft Matter Center and NASA's Advanced Colloids Experiment at the International Space Station. He already published 15 papers in peer-reviewed journals, including Science, PNAS, and Phys. Rev. Lett. He serves as a referee for Phys. Rev. Lett.,Phys. Rev. E,J. Chem. Phys., and Soft Matter.
