      Collapse Overview
      My research is driven by two major factors. First, there is an unprecedented pressure to deliver new and improved diagnostic and treatment options to patients. Second, due to improved understanding of biological intricacies with ever improving molecular assays have placed us in a much better position to look for disease specific biomarkers that once validated can be used in the clinics in order to provide timely and accurate assessment of health status of patients.
