He is also a member of the NUS Pharmacy Programme Advisory Board, and the Ngee Ann Polytechnic Life Sciences & Chemical Technology Advisory Committee.

Mr How holds a B.Sc. (Hons) in Pharmacy and a Master of Business Administration from the National University of Singapore. He completed his pre-registration Pharmacist training at the National University Hospital before venturing into the private sector.

Prof Ng Huck Hui was appointed Executive Director of A*STAR Graduate Academy (A*GA) on 1 April 2017. He oversees A*GA’s talent management and development strategy to nurture young STEM (Science, Technology, Engineering, Mathematics) talent and a strong local pipeline of scientific talent.

He is concurrently the Executive Director (ED) of the Genome Institute of Singapore (GIS). He joined A*STAR as Group Leader, GIS in 2003, before assuming the appointment of Acting ED, GIS in January 2012 and ED, GIS in October 2012. Under his leadership, GIS has grown to be a home for over 250 researchers working on different aspects of human genomics (human genetics; infectious diseases; cancer therapeutics and stratified oncology; human disease models; translational genomics; and computational and systems biology).

Prior to joining A*STAR, Prof Ng was a postdoctoral fellow at Harvard Medical School under the prestigious Damon Runyon-Walter Winchell Postdoctoral Fellowship. Prof Ng is renowned in the field of stem cells, having spent more than a decade in research to understand and uncover the intricacies of gene regulation and how they relate to cell biology.

He was the President of the Stem Cell Society Singapore, a major platform for educating the public on stem cell research. In 2016, he was elected as Associate Member of the European Molecular Biology Organisation, making him the only associate member based in Singapore.

Prof Ng holds adjunct positions at the National University of Singapore (NUS) Yong Loo Lin School of Medicine; NUS Faculty of Science; Nanyang Technological University School of Biological Sciences; and the Singapore Eye Research Institute. He also sits on the boards of Science Centre Singapore and NUS High School.

In recognition of his scientific contributions, Prof Ng has received numerous local and international honours and awards, including the Young Scientist Award (2004); Singapore Youth Award (2005); National Science Award (2007); Junior Chamber International Outstanding Young Persons Singapore Awards (2009); Singapore Youth Award (Commendation Medal) (2010); President’s Science Award (Team Award) (2011); and President’s Science Award (Team Award) (2018).

Prof Ng holds a Bachelors degree from NUS and a Ph.D. from the University of Edinburgh.

Professor Louis Chen is Emeritus Professor at the National University of Singapore (NUS). During his 43 years with NUS, he was Head of the Department of Mathematics (July 1996 to June 2000) and Head of the Department of Statistics and Applied Probability (July 2002 to June 2004). In July 2000, he became the founding Director of NUS’ Institute for Mathematical Sciences (IMS), which he built up into one of the finest in the world. He served as Director of the Institute for 12 ½ years.

For his achievements in his field of study, he was appointed Tan Chin Tuan Centennial Professor (July 2006 to December 2012). In January 2013, he was appointed Distinguished Professor. Internationally, Prof Chen was the first Asian to be elected President of the Bernoulli Society for Mathematical Statistics and Probability (August 1997 to July 1999). He received one of the highest honours when he became President of the Institute of Mathematical Statistics in August 2004, joining the ranks of the Institute's past presidents who are among the world's finest researchers in probability and statistics.

Prof Chen carried out research work in various areas of probability theory and statistics, namely Stein's method, martingale theory, Poincaré inequalities, and in biomolecular sequence analysis in computational biology. In his pioneering work on Poisson approximation in 1975, he developed a method of calculating the probabilities of occurrences of dependent rare events. This method, which is now known as the Chen-Stein or Stein-Chen method, has found wide-ranging applications in many fields, with lasting impact in science and technology. It has developed into one of the most important areas of discrete probability.

Prof Chen obtained his B.Sc. (Hons) in Mathematics from the then University of Singapore (now NUS) in 1964 and his M.Sc. and Ph.D. in Statistics from Stanford University in 1969 and 1971, respectively.

Nicole Lim Pei Pey graduates with Honours (Highest Distinction) in Environmental Studies (BES), specialising in Environmental Geography, where she was placed on the Dean’s List for Academic Year 2016/2017 Semester 2.

Nicole was actively involved in student life and community leadership. She was the Project Director for the BES Sustainable Futures Symposium (2016), an annual event organised with the BES community in partnership with the Rotary Club. She subsequently served as President of the BES Student Committee from 2017 to 2018.

To promote a culture of caring for the environment, Nicole pioneered various initiatives, such as Sustainability+, the first cross-faculty sustainability dialogue in NUS, as well as engagement with secondary school students through a coastal cleanup, green career dialogues, and many other activities.

During her stay at the College of Alice and Peter Tan (CAPT), she complemented her environmental education with community engagement and active citizenship. She was appointed the Vice-President of the Students’ Committee in her second year. In addition, she advocated for greener institutional practices within CAPT, such as the reduction of single-use plastic within the college.

Nicole also assisted in the Cooling Singapore project, a research initiative by the Future Cities Laboratory to investigate the urban heat island phenomenon in Singapore. Stemming from this, she published several books, policy recommendations and science communication videos.

Under the NUS Study Trips for Engagement and EnRichment (STEER) programme, Nicole travelled to Costa Rica and Panama, where she learnt about environmental management and emerging business opportunities in Central America. On another STEER programme to Myanmar, she explored the themes of democracy and sustainable development. She also participated in an overseas field course to Bohol on environmental and conservation challenges in the Philippines.

Nicole is currently working in the field of sustainability, where she creates partnerships and collaborations with businesses, civic society and the public sector through engagement platforms. In the future, she hopes to work at the nexus of rural-urban development, as she believes that environmental and community challenges emerge at this frontier.
