- Professor of Anatomy and Neurobiology
I obtained my Ph.D. degree from Aligarh Muslim University, India.
As a postdoctoral fellow at the Centre du Immunologie du Marseille-Luminy, France, I carried out research on the cloning of cytotoxic T cell-specific gene transcripts. As a postdoctoral fellow and then Research Associate at Mayo Clinic, I carried out research on the characterization and immunogenetics of collagen-induced arthritis in mice model of RA. I then moved to the Division of Rheumatology, Case Western Reserve University, where I expanded my research to include studies on the cartilage homeostasis in health and disease with particular emphasis on OA.
I have also trained several post-doctoral fellows during my tenure at the Case Western Reserve University in Cleveland, and at the University of South Carolina in Columbia, S.C.
At NEOMED, I am supervising a graduate student and training 3 Post-Doctoral Fellows to become independent investigators.
Area of Expertise/Research Interests
My research at NEOMED, funded by NIH, focuses on the role of small non-coding RNAs and novel genes in the pathogenesis of osteoarthritis. I examine the mechanisms that regulate anabolic genes and are disturbed or disrupted in osteoarthritis (OA) using both in vitro and in vivo approaches.
