Associate Professor, Department of Orthopaedic Surgery

Instructor, Dominick P. Purpura Department of Neuroscience

Professional Interests

As a biomedical engineer, my research focuses mainly on mechanobiology or how physical forces and alterations in cell and tissue mechanical properties contribute to physiology, development and disease, especially diabetes. Major research projects include:

  1. Mechanism by which diabetes alters bone cell mechanosensing, signaling and transduction
  2. Bone and sensory nervous system
  3. Mechanism of osteocyte mechanotransduction
  4. Mechanosignaling in osteoarthritis
  5. Role of vascular endothelial growth factor (VEGF) in bone mechanotransduction
  6. Role of junctional proteins in bone mechanotransduction
  7. Role of glycocalyx in endothelial mechanotransduction
  8. Interaction between purinergic receptors and gap junctions in diabetes

Training opportunities are available for students and both research and clinical fellows in my laboratory with respect to each of these project areas.
