Postdoctoral Fellow, 2018-2020, Mechanical and Aerospace Engineering, Princeton University
I am broadly interested in the transport of fluids, particles, bacteria, and chemicals in the environment. My current research is focused on designing multi-scale interdisciplinary experiments to mimic complex interactions in nature and developing physically-based models to predict natural processes. Here is a list of current projects:
There are several openings for graduate students and postdocs. Interested candidates are welcome to contact Dr. Yang directly via email: judyyang@umn.edu.
