2004 Ph.D National University of Malaysia, Environmental Science (Weed Science)
2000 M.Sc  National University of Malaysia, Botany (Weed Science)
1998 B.Sc  National University of Malaysia, Conservation Biology  & Ecology (Botany)


Chuah Tse Seng received his Ph.D. from the School of Environmental and Natural Resource Sciences at National University of Malaysia in 2004. During his Ph.D research, he studied biology and control of glyphosate-resistant and susceptible biotypes of goosegrass. He joined University of Malaysia Terengganu in 2003 as a lecturer. In 2010, he took sabbatical leave to conduct research on exploitation of allelochemicals from weedy plants for sustainable weed management and in the same year, he was promoted as Associate Professor. In 2013, he was appointed as Deputy Dean of Research and Academic Talent at the School of Food Science and Technology.

Research Interests

• Herbicide resistance mechanism
• Weed biology and management
• Herbicidal properties of tropical plants
