Kam W. Leong is the James B. Duke Professor of Biomedical Engineering in the Pratt School of Engineering of Duke University, at which he also holds a joint appointment in the Department of Surgery of the School of Medicine. His research concentrates on understanding and exploiting the interactions of cells with nanostructures for therapeutic applications. Discrete nanostructures in the form of multi-functional nanoparticles are applied to deliver drug, antigen, protein, siRNA, mRNA and DNA to cells for drug, gene, and immunotherapy. Continuous nanostructures in the form of electrospun nanofibers and imprinted nanopatterns are applied to biomaterials design and regenerative medicine applications.
