The NUS Credit Research Initiative (CRI) -- Transforming Big Data into Smart Data

After 14 years of working on the Credit Research Initiative (CRI; http://www.criat.sg), the baton has been passed on June 30, 2023. As its founder and champion all these years, CRI has meant a great deal to me personally, but retirement is inevitable in one's professional journey. I would like to thank many individuals and institutions for offering me their help and believing in this public good undertaking. I wish CRI a continued success.

CRI of the National University of Singapore operates on a delivery platform that offers freely accessible, daily updated term structures of default probabilities and actuarial spreads on over 90,000 exchange-listed firms in over 135 economies globally. Founded on a credit rating reform drive and launched in 2009, CRI was my constructive response to the great global financial crisis, intending to also serve as a live platform for research into Big Data Analytics and digital finance. The CRI platform has been operating in a Wikipedia style – inclusive, organically evolving, and welcoming participations from the broader research and financial community.


Criat -- Converting Smart Data to Actionable Data

In 2017, I co-founded Criat (CRI Analytical Technologies; http://www.criat.sg), a Singapore registered FinTech company and an NUS spin-off specializing in Deep Credit Analytical Technologies. The company provides DeepCredit® analytical products and services to financial institutions with its unique blend of interpretable AI/Big Data Analytics with the established econometric/statistical methodologies for dynamic models. I have been serving as its non-executive chairman since the founding.
