Research DescriptionCurrent projects include 1) identifying and applying biomimetic strategies to create biointerfaces for soft and hard tissue regeneration 2) biomolecular control of the foreign body reaction, with particular emphasis on the macrophage-mediated inflammatory response to biomaterials, 3) mechanistic studies aimed at developing novel therapeutic targets and approaches for treating ectopic calcification in disease and medical devices
