Research Interests for Chuan-Hua Chen

Our research deals with experimental and theoretical investigations of small-scale physicochemical hydrodynamics, where transport and interfacial phenomena closely interact with each other. By manipulating surface tension actively and passively, e.g. using electric fields and surface structures, we are develop innovative solutions for applications ranging from bioanalytical assays to microelectronics cooling.
