Listed below are some research topics that I currently want to study. Unfortunately time limitations exists and many of these nice open problems will stay on my "wish list" for some time. These topics may be suitable projects for both serious BSc(Hons) and graduate students. (More information regarding these project areas is available from other links of my home page or by contacting me directly.)

- Parallel graph algorithms for both multi-core CPUs or high-performance GPUs.
- Develop "good" construction techniques for generating sparse bounded-degree broadcast graphs.
- Various network design problems: (1) for directed graphs, (2) planar networks, (3) fault-tolerant, (4) symmetric routing protocols, (5) relaxed time, ...
- Find a feasible algorithm for enumerating graphs of bounded pathwidth and treewidth. (E.g., invent canonic forms within the basic t-parse operator/algebraic representations.)
- How to generate random graphs of bounded path/treewidth.
- Compare and invent practical data clustering algorithms. What heuristics work best for different input?
- Explore quantum computing algorithms for combinatorial hard optimization problems.
- Experimental testing of heuristics for graph coloring and other hard graph problems.
- Distributed algorithms, possibly using membrane computing models.
- Theory and practice of graph databases.

Several other practical projects are available and I am happy to discuss the possibility of pursuing other topics.
