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 studies 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 studies 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. His current research areas include:
- Applications of bio-inspired superhydrophobic surfaces in marine engineering for anti-biofouling, anti-icing, and energy saving;
- Biofouling and attachment mechanism of marine micro-organisms on roughed and bubbled surfaces;
- Mechanism of drag and noise productions in turbulent boundary layers over high-speed vessels;
- Mechanism of group cohesion maintenance by social animals in turbulent and uncertain environments;
- Holographical imaging of human cells and cancer detection;
- Long-term three-dimensional tracking and monitoring of the foraging actives of seabirds.
Dr. Ling’s work has been published in several high-impact journals including Nature Ecology and Evolution, and Nature Communications.
