Nhan Phan-Thien. Nhan Phan-Thien, Fellow of the Australian Academy of Science (born October 31, 1952, in AnGiang, Vietnam), is an emeritus professor of mechanical engineering at the National University of Singapore, Singapore. He has been an associate editor of Physics of Fluids since 2016, currently one of its Deputy Editors since 2023, and an editorial board member of Journal Non-Newtonian Fluid Mechanics. He held a Personal Chair at 
University of Sydney [1991-02] and head of the Mechanical Engineering Department National University of Singapore [2016–19]. His contribution to the rheology field includes the PTT (Phan-Thien – Tanner) model for viscoelastic fluid (1569 citations) and its variant (694 citations). He is the author and co-author of several books in rheology

Education
Phan-Thien graduated from the University of Sydney, Sydney Australia, with a BEng (Mech. Eng. 1st Honours, University Medalist, 1975). He later completed a PhD degree at the University of Sydney, the Department of Mechanical Engineering in 1979.

Career
He has been a faculty member in mechanical engineering at University of Newcastle (Australia) (1978–80) and at the University of Sydney, Sydney, Australia (1980–02). At the University of Sydney, he held a personal chair (1991–02). He was a professor of mechanical engineering at the National University of Singapore, Singapore (2000–04, 2011–present). He was the founding chair in Bio-Engineering Division, which later becomes known as Biomedical Engineering Department at the National University of Singapore. He has held visiting professorships in Los Alamos National Laboratory, New Mexico, US, Caltech, California, US, and Stanford University, California, US, a Qiushi Chair Professor at Zhejiang University, Hangzhou, China, an adjunct professor at the University of Southern Queensland, Queensland, Australia, and an honorary professor at the University of Sydney, Sydney, Australia.

Research
Phan-Thien and his group have published extensively on the rheology of polymeric liquids, computational and constitutive modelling.
