2. Academic Background
 B.S of Electrical Engineering (Xi’An
JiaoTong University, China)
◦ Dissertation: “DS1302 Chip Coding and Encrypting
Study in Contact-less IC Card System”
 PhD of Computer Science (Nanyang
Technological University, Singapore)
◦ Dissertation: “Graph-Theoretic and Geometric
Optimizations in Communication Networks”

3. Technical Skill Highlights
 Computer Science
◦ Mathematical modeling, optimization and simulations
◦ Algorithm prototyping, code developing
 Optics
◦ Device design, setup and alignment
◦ Monte Carlo simulation
 Good knowledge in broad range of general
science and technology

4. PhD Researches
 My PhD research work is composed of four
projects:
a. Optimal Wavelength Converter with Guaranteed Wavelength Usage
b. Load-Balanced Clustering in Wireless Sensor Networks (WSNs)
c. Worst-case and Best-case k-coverage Problem in WSNs
d. Generalized Study on Movement-assisted Sensor deployment problem
 These four projects can be classified by
approaches used:
◦ Graph-theoretic approach
◦ Geometric approach

5. Graph-Theoretic VS Geometric
Optimizations
Graph-theoretic approach Geometric approach
Formulate the original Study the measurable properties
problem into “graphs” (tree, of figures (size, shape, angle,
path, star, ring, etc) position, etc)
A graph is composed of edges Deals with problems of
and vertices (nodes) computing geometric objects
