I am a pathologist who specializes in molecular genetic pathology and hematopathology. I also have an interest in developing new genetic tests for leukemia and lymphoma.

My molecular pathology work involves looking at mutations in samples from patients with cancer to diagnose, monitor, and help guide their therapies. This information also helps ensure each patient’s treatment plan is personalized to their unique cancer. As part of the Hematopathology Service, I integrate clinical and genetic information with microscopic and flow cytometry evaluation of patient tissues to diagnose blood cancers such as leukemia and lymphoma. 

My research is focused on identifying the genetic changes that drive leukemia and lymphoma to uncover prognostic and therapeutic markers.  This work dovetails with my clinical test development role in the Diagnostic Molecular Pathology Service.
