B.Sc. (CUHK), M.Phil. (HKUST), Ph.D. (UIUC)

Alan, CHENG Ho-lun 鄭浩璘 was born in Hong Kong. He completed his Bachelor's degree in computer science at the Chinese University of Hong Kong and M.Phil. in computer science at the Hong Kong University of Science and Technology. He then began his doctoral work at the University of Illinois at Urbana-Champaign, completing a Ph.D. in computer science in May 2002, with thesis titled "Algorithms for Smooth and Deformable Surfaces in 3D" (pdf)

 under the supervision of Prof. Herbert Edelsbrunner. (Thus, my Erdos number is 3 and here is my mathematical genealogy.)

Ho-lun's interests include computational geometry, parametric surfaces, computer graphics, visualization. He was a teaching assistant during his master degree and received the Best Teaching Assistant Award in 1996 at HKUST. During the Ph.D. years, he was a visiting scholar in the BioGeometry Center in Duke University.
