My research focuses on using selective, high-affinity molecular interactions to reversibly bind molecules to polymers for use in drug delivery and tissue engineering.  For applications in drug delivery such constructs should provide temporal control over drug release as well as afford the opportunity to refill the drug delivery device in
situ, eliminating the need for explantation followed by implantation of a new device.  In tissue engineering applications these constructs provide both temporal and spatial control over the expression of bioactive molecules at the biomaterial surface, which can be used to guide cell function.
