INTERN EXPERIENCE

AMD DirectX Driver Group, May - Sep. 2008 & June - Aug. 2009
--Constructed DirectX driver functional testing framework, developed testing applications, and designed test plans.
--Focused on GPU parallel computing, and multithreading rendering.

RESEARCH & DEVELOPMENT EXPERIENCE

Worcester Polytechnic Institute, Jan. 2005-Present
Developed and released XmdvTool, a cross-platform software for visual analytics of relational data.
--Re-architected this open-source software package using object oriented design and visualization pipeline with a focus on improving the reusability and extensibility of the source code. Wrote 30,000 lines of code using C++, OpenGL, Qt, 75% of the whole system. Managed the release on sourceforge.

Exploratory visualization for data streams
--Designed and implemented a real time system to visually convey pattern changes on data streams using C++, Qt and OpenGL. Connected to a live stream via FTP protocol. Involved multithreading and socket programming.
--Developed lossy data compression algorithms to store streaming data which keep data pattern changes.
Visualization of data quality for relational data
--Developed a system to compute and visualize data quality for relational data using C++, OpenGL, and Tcl/Tk.
Course Projects
--Employed hash table to reduce by 98% the time cost of solving a sliding puzzle with the A* search algorithm.

WORK EXPERIENCE

Software Engineer, Sinotrust Intl. Info. & Consulting (Beijing) Co., Ltd.,  Nov. 1999- Jul. 2000
--Project lead of a credit management system to enable companies to share credit information of small business.
--Involved in the whole life cycle of software development, .from requirement analysis to testing.
 

Instructor & Researcher, University of Science and Technology Beijing, Mar. 2000 - Sep. 2004
--Taught C Programming Language, Software Engineering, Database Management Systems, and Computer Graphics.
--Designed and implemented a web-based industrial network management software system using Java Applet. It has been installed in many plants in China as a part of their automation control solutions.
--Developed a real time system to monitor boiler flame images and communicate with an alert system using VC++. It is laborsaving and has been installed in a chemical plant in Beijing as a key part of the security system.
--Developed a 3D tree rendering system which simulates genetic variability during reproduction (VC++ & OpenGL).
