An associate professor of mathematics from the University of Maryland at College Park, Sijue Wu works in the general field of harmonic analysis and partial differential equations. Recently, Wu’s research has focused on nonlinear equations from fluid dynamics. Using harmonic analysis technique, she has established the local well-posedness of the full two- and three-dimensional waterwave problem. This settled a longstanding problem.
As a Radcliffe fellow, Wu will continue her study of vortex sheet dynamics, a phenomenon that arises from the mixing of fluids, such as occurs during aircraft takeoffs. A vortex sheet is the interface separating two domains of the same fluid across which the tangential component of the velocity field is discontinuous. Achieving a better understanding of the motion of a vortex sheet requires proper mathematical modeling; Wu’s long-term goal is to establish a successful model. She will also work on the boundary layer problem, another problem arising from fluid dynamics.
Wu earned her BS and MS in mathematics from Beijing University in China and her PhD in mathematics from Yale University. Her academic honors and awards include the 2001 Ruth Lyttle Satter Prize in mathematics and Morningside Silver Medal in mathematics. Wu is an invited speaker for the 2002 International Congress of Mathematics in Beijing.
