Research Interests:
Molecular interactions, assembly, and signaling of adhesive intercellular junctions in development and disease.
The main focus of the laboratory is to reveal mechanisms of adhesion between keratinocytes and vascular endothelial cells in the context of skin biology. Specifically, we are investigating the functions and regulation of the cadherin family of adhesion molecules. These molecules mediate homophilic interactions and play key roles in the patterning of tissues during development and in the maintenance of tissue architecture in adults. A major focus of our studies is to understand how cadherins are modulated by endocytic membrane trafficking pathways, and how the dynamic presentation of adhesion molecules at the plasma membrane is regulated during development and disease.
