Research Interests 
 
Professor Ren’s research interests are in applied mathematics and scientific computing, with a focus on rare events, multiphase flows, and the moving contact line problem.  His work has contributed to establishing mathematical foundations and developing effective computational methods – such as the string method – for studying rare events, as well as resolving the moving contact line problem, a long-standing problem in classical fluid mechanics, through modelling and simulations.

 
Key Services 
 
Professor Ren has served on multiple committees at NUS, including the Faculty Promotion and Tenure Committee and the University Promotion and Tenure Committee. He has been chairing the Search Committee in the Department of Mathematics and currently serves as the Deputy Head (Research and Academic Affairs) of the Department. He is also an Associate Editor of the SIAM Journal on Applied Mathematics.
