Combinatorial Biomaterials and Biointerface, Stem Cell Engineering, Engineering Aspect of Cardiovascular Medicine, and Tissue Engineering.

Current Projects

The major research areas in the Sung lab are polymeric biomaterials-based matrix engineering, cellular engineering, tissue engineering, and therapeutic engineering which involve a multifaceted approach that combines state of the art biomaterial systems, engineering tools, and chemical/biochemical/biological methodologies. The research goal of the Sung lab is to identify the underlying mechanisms by which cells and tissues interact with polymeric matrix from nano to organ scales and coordinate dynamic physicochemical/biological signals to change their microenvironments, and to apply this knowledge to develop the next generation of polymeric biomaterials for regenerative medicine and medical device technologies.
