Dr. Weiwei Deng is a Professor in the Department of Mechanics and Aerospace Engineering at the Southern University of Science and Technology (SUSTech). Prior to joining SUSTech, he was a tenured associate professor at Virginia Tech (2015-2017) and an assistant professor at the University of Central Florida (2010-2015). He received his Ph.D. in Mechanical Engineering from Yale University in 2008 and B.S. from Tsinghua University in China. Dr. Deng’s general research interest is the fluid dynamics of low-dimensional liquid subjects (droplets, jets, and films) and their applications in additive manufacturing. His group’s work has been recently featured as the cover article of Physical Review Letters. He is the recipient of National Science Foundation CAREER Award.
