Molecular Biomaterials for Tissue Repair
in our laboratory focuses on designing novel synthetic biomaterials and
investigating how they may be engineered to direct biological
processes. We are particularly interested in understanding how
assemblies of proteins, peptides, polymers, and conjugates of these
molecules can be constructed into synthetic extracellular matrices
capable of directing cell behavior in vitro (e.g. as defined 3-D
culture media) or in vivo (e.g. as scaffolds for Regenerative
Medicine). Our research questions center around three interconnected
1) Investigating structure-function relationships that determine how
molecular design impacts folding and assembly into nanostructures
(fibrils, networks, and gels), and how the physical, chemical,
mechanical, and biological properties of the assembled material may be
subtly modulated through choices in molecular design.
2) Understanding how cells interact with defined synthetic
extracellular matrices so that the matrices can be systematically tuned
to favor particular cell phenotypes.
3) Understanding how molecular design and assembly state directs
tissue-level or organism-level responses. We are primarily interested
in understanding how assemblies of peptides and proteins engage
inflammatory and immune responses so that they can be engineered to
modulate these processes locally. Although these questions and
approaches are applicable to many tissues, we are currently focusing on
epithelial and endothelial tissues, as these tissues mediate the
interfaces of physiology.
