Xinsheng Sean Ling is Professor of Physics at Brown University's College of Arts and Sciences, where he has been a faculty member since 1996. A Fellow of the American Physical Society since 2005, he maintains active research in multiple areas of experimental condensed matter physics and has held visiting positions at Delft University of Technology, Wuhan University, and Soochow University in China.
Dr. Ling's educational background includes a BS from Wuhan University (1984), MS from the Chinese Academy of Sciences (1987), and PhD from the University of Connecticut (1992). He completed postdoctoral research at Yale University (1992-1994) and the NEC Research Institute (1994-1996). His research spans three primary areas: colloidal physics, vortex physics in superconductors, and nanopore DNA sequencing.
- His work in colloid physics focuses on 2D colloidal systems, studying defects, glass transitions, and phase behavior in both spherical and rod-shaped particles.
- In vortex physics, he has made significant contributions to understanding the peak effect and Bragg glass phase transitions in type-II superconductors.
- His nanopore research explores DNA sequencing technologies with a focus on kinetic proofreading mechanisms to improve sequencing accuracy.
His recent publications (2019-2022) demonstrate continued activity across these fields, with particular emphasis on 2D colloidal systems and their phase transitions, Kondo physics in superconducting materials, and nanopore fabrication techniques. His work shows a consistent pattern of combining experimental approaches with theoretical frameworks to address fundamental questions in condensed matter physics.
Scientific Recognition:
- Fellow, American Physical Society (2005)
- Guggenheim Fellow (2002)
- Alfred P. Sloan Fellow (1998)
- Research Corporation Innovation Award (1998)
- China Thousand-Talent Plan Visiting Professor (2015-2017)
- Fulbright U.S. Scholar to Argentina (2025)
Dr. Ling has successfully secured significant research funding, including an active NSF-DMR grant (2022-2025) on thermally activated dynamics in 2D colloidal systems. His collaborative network includes prominent physicists such as Nobel Laureate J. Michael Kosterlitz and Robert Pelcovits, reflecting his standing in the condensed matter physics community. He has also contributed to educational efforts at Brown through teaching undergraduate physics courses including Basic Physics, Foundations of Mechanics, and Introduction to Relativity, Waves and Quantum Physics.
