Xiuzi Ye is currently a Principal Engineer at SolidWorks Corporation, a company developing PC and Windows/NT based 3D CAD software product and a subsidiary of Dassault Systemes (CATIA), France. He is also an Affiliate Research Scientist at Design Laboratory, Massachusetts Institute of Technology (MIT). Dr. Ye is responsible for the company's complex geometry design in a feature and parametric/constraint based solid modeling environment, including constraint and dimension driven complex curves, surfaces and solids design, interrogation and integration. These included creation and interrogation of generalized and variational swept and lofted objects, tangency and curvature matching of surfaces and the integration of complex curves and surfaces into solids. As an affiliate to MIT, he is also involving academic and research activities in MIT Design Laboratory. He served as a Member of Doctoral Thesis's Committee of several Ph.D. candidates at MIT Design Laboratory.
Prior to this, from 1994 to 1995, Dr. Ye was a Postdoctoral Research Associate at MIT Design Laboratory. His research at MIT addressed (1) data integration among CIM systems. He developed an information model for marine propulsors. This model intends to be an application protocol for the modeling, representation, integration and exchange of product data from design, manufacturing, inspection, analysis and other life-cycle activities of marine propulsors based on the STEP mechanisms. It is the base for the integration of marine propulsor related computer-aided automation systems and for the implementation of a standardized propulsor database which stores the product data and their neutral descriptions for marine propulsors; (2) the geometric design of surfaces with functional hydro- and aerodynamic constraints; (3) robust issues of solids modeling based on interval arithmetic; and (4) the development of continuous multi-dimensional geographical database systems.
Between 1989 to 1994, he was pursuing his Ph.D. at CAD Laboratory of Technical University (TU) of Berlin, Germany. Dr. Ye's doctoral thesis research at TU Berlin addressed the problems of geometric construction and visual interrogation of smooth free form rectangle-grided and multi-sided surfaces by tangent-plane and curvature continuous interpolation of curve meshes using tensor-product polynomial Bezier patches. This design methodology is to simulate current industrial design practice where surface definitions are usually produced from drawings in which suitable sets of curves are first designed and adjusted carefully to yield a fair surface. These methods can easily be integrated into the state-of-the-art CAD/CAM systems. The novel features of his thesis included formulation and solutions of the compatibility conditions of arbitrary numbers of surface patches joining at a common point, and the use of possibly low polynomial degrees of the surface patches. Dr. Ye's research at TU Berlin also included information technology, product data modeling, conversion and exchange based on the STEP standard.
Between 1987 to 1989, Dr. Ye was a Research Engineer at the State Key Laboratory of CAD/CG at Zhejiang University, China. He involved in the development of the geometric modeling system MESSAGE (Modeling Entities using Solids, Surfaces and Geometric Entities). He was responsible for the system's surface modeling and related graphical interface. The project was part of a Chinese National Science and Technology Progress Award. He also involved in an industrial project on the fairing of an aircraft fuselage during his graduate study.
Dr. Ye has authored and co-authored over 30 technical journal and conference papers. He serves as a member of the editorial board of Computer Aided Drafting, Design and Manufacturing Journal, and a member of the International Program Committee of IASTED CGIM'98 and CGIM'99 (International Conferences on Computer Graphics and Imaging).
