Aaron Watkins James, M.D., Ph.D.
Associate Professor of Pathology
Expertise: Orthopaedic Pathology, Pathology
Research Interests: Bone biology; Osteogenesis; Skeletal repair; Mesenchymal stem cells; Osteosarcoma
Dr. James received his M.D. with thesis from the University of California, San Francisco with research at Stanford University. Dr. James performed his residency in Anatomic Pathology and fellowships in Orthopaedic Pathology and Surgical Pathology at the University of California, Los Angeles. He received his Ph.D. in bone biology and osteoprogenitor cells from University of California, Los Angeles.
Dr. James is a dual physician-scientist and bone tissue pathologist, with research interests in bone tissue regeneration and repair. Current research interests include perivascular mesenchymal progenitor cells for bone tissue engineering, and novel growth and differentiation factors to speed bone repair. Other interests include an examination of the supporting tissues for osteogenesis and bone repair, including the peripheral nervous system, as well as the study of bone-forming tumors (osteosarcoma) and the development of novel therapies. His work requires the intersection and collaboration of multiple disciplines, including collaborations within Pathology, Orthopaedic Surgery, Plastic and Reconstructive Surgery, Dental Sciences, Engineering, Bioengineering, and Material Sciences.
