David Gu is an associate professor (with tenure) at the Department of Computer Science, Stony Brook University. He received his Ph.D degree from the Department of Computer Science, Harvard University in 2003 and B.S. degree from the Tsinghua University, Beijing, China in 1995.


David Gu’s research focuses on applying modern geometry in engineering and medical fields. With his collaborators, David systematically develops discrete theories and computational algorithms in the interdisciplinary field: Computational Conformal Geometry, and apply them for solving real problems, such as global surface parameterization in graphics, deformable shape registration in vision, manifold spline in geometric modeling, curvature convergence analysis in geometric processing, efficient routing in networking, brain mapping and virtual colonoscopy in medical imaging, and so on.



David Gu is a recipient of Morningside Gold Medal of Applied Mathematics, International Congress of Chinese Mathematician (ICCM)2013; the Research Excellence Award, Computer Science department, Stony Brook University, 2010; Gaheon Award: The Best Paper in International Journal of CAD/CAM of 2009; Best Paper Award: The 10th International Conference on Computer Aided Design and Computer Graphics, 2007; National Science Foundation (NSF) Faculty Early Career Award, 2005.
