1.     Neuroprotection and neurogenesis   
2.     Calcificiation of soft tissues and the role of vitamin D
3.     Integrin and molecular signaling pathways

     My work has primarily focused on Focal Adhesion Kinase, a major tyrosine kinase involved in integrin signaling, and its role in regulating a number of key cytokines in the brain.       Dysregulation and altered signaling after or during neurodegenerative conditions might make this molecule an important pherapeutic target.

    I have also taken a keen interest in the role of Vitamin D (Calcitriol) in the process of calcification of soft tissues, such as the brain.
