Chong Chi Tat

Chong Chi Tat is university professor and director of the Institute for Mathematical Sciences at the National University of Singapore (NUS). His research interests are in the areas of recursion/computability theory.

Academic career
Chong received his BSc with distinction from Iowa State University and his PhD from Yale University. He began his career in University of Singapore, the predecessor of NUS, as a lecturer in 1974. He was subsequently promoted to senior lecturer (1980–1985), associate professor (1985–1989), and professor (1989–2004). Chong held many administrative leadership positions, including vice dean of science (1985–1996), department head of information systems and computer science (1993–1996), deputy vice chancellor, deputy president and provost (1996–2004); and department head of mathematics (2006–2012). In 2004, Chong was named the second University professor of NUS, the highest honor bestowed upon a very small number of its tenured faculty members.
