Research summary (KS Leung)

Research Fields: Evolutionary Computation, Data mining, and Bioinformatics

Representative Projects and Results:

(1)   Finding DNA Markers of Hepatitis B Virus (HBV)

• Supported by an ITF grant of over $4.4 million+ 2 million from drug industry and several other small grants
• Cross departmental project and top international collaborators
• Largest project of its type
• Impact: Over 20% and 10% of Mainland and Hong Kong Populations are carriers and many will turn into lever cancer. About 1 million people died of related diseases worldwide each year.
• Results: We found some significant markers which can be used to diagnosis potential lever cancers caused by Hepatitis B   with around 80% accuracy. Patents have been obtained through RTAO. A new approach based on Information Gain, non-linear integral and rule learning algorithms have been adapted to achieve this. New subtypes of  HBV  were also discovered.

(2)   Dynamic Cancer Drug Scheduling (in time sequences) for Chemotherapy

•  We have created a multi-mode (solutions), multi-drug optimizer for Cancer Chemotherapy, so that the Oncologist (Dr Mok) can have a choice of several (sub-)optimal solutions to consider for the patients. The approach is based on a new memetic Evolutionary Algorithm working on a set of dynamic differential equations modelling the drug responses.
• Support by a RGC Earmarked Grant

• We have discovered several cancer drugs through drug repurposing.
• We have developed idock (https://Github.com/HongjianLi/idock ), a multithreaded virtual screening tool for flexible ligand docking. It outperforms AutoDock Vina by at least 8.69 times and at most 37.51 times in terms of docking speed.
• We have also developed istar (http://istar.cse.cuhk.edu.hk ), a SaaS (Software-as-a-Service) platform for idock, igrep and other programs. Users can submit jobs on the fly at our web site without software installation.
• We are currently working on GPU acceleration and ligand synthesis.
• Collaborating with Professor Hsiang-Fu KUNG's research group, we are laboratory testing a newly discoveried peptide based vaccin for Hand, Foot and Mouth disease with promising results.

(5)  Genetic Parallel Programming

• Supported by 2 RGC Earmarked Grants
• We have found that parallel programs can be evolved (learnt) faster than sequential ones and have developed a completely new framework to evolving parallel programs. It forms a brand new approach in the field of Genetic Programming.  It has been used successfully in many applications including hardware design. We have some exciting new results which can beat most of the existing state-of-the-art algorithms in small circuits’ synthesis. Hopefully we can scale it up!

i.   Senior Engineer, ERA Technology, England: Project leader for several international R&D projects (80-84)
ii.  System Analyst, Central Electricity Generating Board, England: Responsible for planning, design and coding 
       of the software of electrical system and generators for nuclear power station real time simulator projects.(84-85)
iii. Managed and developed 8 major computer hardware and software systems) e.g.:

• PI: e-Health Platform with various health sensors such as wireless wearable ECG sensor with AI monitoring developed by our group
• Co-PI: An integrated web-based air pollution decision support system with 10 different plug-and-play pollutant sensors, including PM2.5, CO2, radiations, etc.

Our group will move our attention to creating new algorithms for high impact real-life genomic problems such as gene networks acquisition, large scale data mining on Transcription Factors and Transcription Factor Binding Sites, multiple gene sequence alignment, marker extraction, and functional region identification problems. We have been working on new data structures, indexing and EAs with dynamic time warping (DTW) to solve these problems. Prof MH Wong who is an expert in database and DTW has been contributing in this new drive. We are working on real life Genomic problems on Hepatitis-B, HIV and Diabetes. Drug/Ligand discovery is also vigorously being pursued.
