RESEARCH

The focus of my clinical research is the development of sequence-based testing for rare disorders, development of next generation sequencing panels for rare disorders, development of custom microarrays to address copy number variants, and validation and implementation of algorithms for interpretation pathogenicity of sequence variant of unknown clinical significance. 

My current research interest focuses on pharmacogenetics (the study of the effect of genetic variation on drug response).  Current studies include breast cancer and tamoxifen, clopidogrel (Plavix) and CYP2C19, and colon cancer and associated biomarkers.

Previous to joining the clinical molecular diagnostic lab, I was a member of the Hayflick research lab where I investigated the genetic basis of Pantothenate Kinase-Associated Neurodegeneration disorder and the molecular mechanism of disease pathology.  As a graduate student, I investigated the genetic basis of peroxisomal disorders resulting in the cloning of a gene of interest and characterization of the molecular mechanism of that associated protein.
