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.
