Serdar Kuyucak (born 19 February 1954) is a Turkish-born Australian physicist, an Associate Professor at the University of Sydney, Australia. His research interest include the study of ion transport across membrane channels using Brownian and molecular dynamics (BD and MD) methods and the solution of spectrum generating algebras (interacting boson model, vibron model) using the 1/N expansion method, and their application to problems in nuclear and molecular spectroscopy.
