Singapore’s top local university, the National University of Singapore (NUS), is currently ranked 22nd in the 2013 World Reputation Rankings published by the Times Higher Education (THE). However, there’ve been reports of unhappiness at NUS due to the disproportionately high number of foreign faculty members over there.
While the main complain seems to be discriminatory hiring (when a foreign recruiter hires people from his homeland), I have a far simpler and better explanation on why there are so few Singaporean academics. Singaporeans don't want to pursue the path of academia.
It's that simple. We Singaporeans just don't care about such things. We care about making money; doing research and writing papers...not so much. Forget about the universities, even in companies, you will see few Singaporeans in their R&D departments.
Generally speaking, Singaporeans are just not interested in such things. The fact that this happens at a famous university makes no difference. Singaporeans will be Singaporeans.
