Research Area

Regenerative therapies for the treatment of equine musculoskeletal disorders. In particular, my laboratory is focused on understanding the immunologic and immunomodulatory properties of both mesenchymal and induced pluripotent stem cells. Such knowledge is critical for potential allogeneic “off the shelf” stem cell therapy which would allow us to treat our patients at the time of diagnosis rather than having to wait several weeks to months to culture stem cells from that patient.
