Department Profile, Google Scholar, Curriculum Vitae 


PhD, Johns Hopkins University, 2017

MS, Johns Hopkins University, 2013

BS, University of Science and Technology of China, 2011

Research Interests
  • Experimental fluid dynamics in turbulence, boundary layers, multiphase flows
  • Super-hydrophobic surfaces and the wetting dynamics
  • Collective behavior such as bird flocks, fish schools, human crowds and cell colonies
  • 3D Imaging technologies using digital holography and stereo-imaging


Dr. Ling is currently an Assistant Professor in Mechanical Engineering at University of Massachusetts Dartmouth. He received his Ph.D. from Johns Hopkins University in 2017, where he studied the drag reduction of super-hydrophobic surfaces in turbulent flows. Before joining UMass Dartmouth, he was a Postdoc at Stanford University from 2017 to 2019, where he studied the collective behavior of natural bird flocks.

Dr. Ling is broadly interested in fluid dynamic problems at the interface of material, biological and environmental sciences. His lab focuses on the development of novel imaging technologies to characterize fluid flows, as well as animal movements in complex environments. His overarching goal is to uncover the underlying physical laws, and harness them to solve the critical energy and environmental issues in our society.
