Research Profile


Research Interests

My interests are to understand how cells’ microenvironment contributes to disease progression. Changes in the microenvironment in the human body are defined, at least in part, by molecules of the extracellular matrix (ECM) and ECM interactions with cell surface signaling receptors called integrins. Our recombinant protein technology has identified roles of ECM interaction on integrins in cell adhesion, migration, and cell death by apoptosis in disease states such as degenerative articular joint disease, diabetes, and cancer. Understating the complex relationship of ECM activation of cellular signaling pathways in diseased and healthy tissues is expected to provide opportunities for novel drug design and patient treatments.
