Clifton's Homepage

Clifton is at NCS Group, working on artificial intelligence, machine learning, and advanced analytics under NCS Digital. He leads a team of more than 30 highly capable data scientists, and mentor them in their activities. For government and commercial customers, the team tries their best to:

1. understand their "Jobs to Be Done", particularly in public safety, public works, and insurance domains
2. learn from the top data scientists
3. innovate and experiment with style

In my free time, I volunteer professional services to events, conferences, and journals (related to data mining/analytics, security and health informatics). Was also part of teams which won some analytics competitions.

You can:

- email me at c...@ncs.com.sg if you are a Singaporean data scientist looking out for job opportunities; or to exchange knowledge on analytics, events, and competitions

connect with me at LinkedIn or Google Scholar if we know each other professionally

Previously, I was at SAS Institute Pte Ltd, working on SAS® Analytics (mostly in security intelligence). My specialization was Big Data analytics in public security (attack and disaster preparation/recovery/response; cyber security; internal security; and predictive policing) and fraud (government, banking, and insurance).

Before SAS, my role was a data scientist at the Data Analytics Department (DAD) (formerly known as Data Mining Department), under Institute for Infocomm Research (I²R), Agency for Science, Technology and Research (A*STAR), Singapore. My analytics experience acquired there includes web monitoring of companies and technologies, assistive technology for people with dementia, and mobile phone activity recognition. I also worked on real-world, energy-related, analytics projects to improve parts of the smart grid and other Big Data applications. Together with my collaborators, we had published a few technical papers on various industry applications of data mining/analytics, such as fraud detection and activity recognition; and my favorite analytics tools at that time included R, WEKA, and MySQL.

Prior to I²R, I was a research fellow at the Data Mining Laboratory, Department of Industrial Engineering, Seoul National University, South Korea.

My PhD (on identity crime detection) and bachelor's (first class honors) degrees are from Clayton School of Information Technology, Monash University, Australia.
