Research Summary

Our laboratory focuses on engineering functional biologic replacements to repair damaged or diseased tissues in the body. We use the complex signals that are implicated in tissue morphogenesis, repair, and homeostasis as a template for the development of innovative biomaterials for tissue regeneration. Through the precise temporal and spatial presentation of soluble bioactive factors, mechanical forces, and biomaterial physical and biochemical properties, we aspire to create microenvironments that regulate cell gene expression and new tissue formation. Some areas of active investigation include controlling stem cell differentiation, delivering bioactive factors sequentially, developing spatially patterned constructs, understanding cell-cell interactions, and determining mechanical influences on cell function.
