Senior Lecturer in Computer Science

Lecturer in Computer Science

Postdoctoral Researcher - I led a team of seven people (one research associate, three postgraduate and three undergraduate students) in research and development of Fluency desktop publishing system for the national project entitled "Building High-Speed, Large-Capacity Information Processing Technology by A New Principle" under the Core Research for Evolutional Science and Technology (CREST) Program.

Research Assistant - I involved in the research and development of multimedia coding, retrieval and presentation technologies based on the Fluency Information Theory proposed by our research group.

Senior Computer Officer - I managed a team of ten computing/technical staff providing end-user, instructional, and research support to faculty and staff in the School of Business & Management at the HKUST. My duties included overseeing the daily operations of the School's laboratories, liaise with the University's Computer Center, prepare and execute operations plan, administer inventory control, provide technical advices to the Dean of the School on sourcing and timing of hardware/software acquisitions, and manage the progress of applications development.

Computer Officer - My duties included the administration and monitoring of computing equipment installed in the Research Center at the HKUST for the government funded Operations Windshear Warning System (OWWS). The types of equipment included high-end graphics workstations from Sun Microsystems, Silicon Graphics, and Digital Equipment Corp. Real-time sensor data came in through modems connected to the Automatic Weather Station (AWS) located at each of the remote sites on the Lantau Island, Hong Kong, as well as from the Hong Kong Royal Observatory. Custom designed software was being used to display these incoming data on workstation displays for real-time analyses and diagnostics.

Computer Officer - My responsibilities included both administrative and technical tasks. On the administration side, I served as the administrator of the Electronic Notice Board system and the Student E-mail Accounts system available on our Center's computers. Other tasks of similar nature included software vendor contacts and the preparation of Budget Requisitions for new purchases and upgrades. On the technical side, I was responsible for data management routines in supporting instruction such as administering the Sybase and the Oracle Relational Database Management System.

Consultant - As a consultant, I provided technical assistances on the in-house developed Ship Planning System for container loading/unloading operations to a team of computing and operations staff.

Systems Analyst - I co-led a group of six programmers with another systems analyst in the development and support of an in-house developed Ship Planning System for real-time container loading/unloading operations. This system was successfully put into production on Sun Microsystems' Sparc 2 platform in January 1992. Prior to this project, I was involved in the development of the Terminal Operations Planning System (TOPS) for optimization of ship-to-berth scheduling using a constraint logic programming language called CHIPS, which stands for Constraint Handling In Prolog.

Graduate Assistant - At the Center for Computing and Information Technology, my duty was to assist the university community in the use of computing facilities through walk-in and phone-in consulting.

Programmer - At the Cornell Theory Center, I assisted a research scientist in providing IEEE floating point arithmetic support for a simulator of FPS T-Series parallel supercomputer as well as investigating the low level communication requirements between this supercomputer and its Gould 9050 host.
