Get to Know Me

I am a clinical hematologist with special expertise in coagulation. My practice encompasses the whole spectrum of non-malignant blood conditions, including thrombosis, bleeding disorders and anemias. I have particular interests in cancer-related disorders of hemostasis, clonal hematopoiesis, genomics and machine learning. My recent research work includes an assessment of how cancer-specific genetic alterations affect the risk of thromboembolism, and application of this knowledge to predict clinical events using a statistical model.  I also teach medical students, residents, and fellows.

What I Do at MSK

I'm a hematologist (HEE-muh-TAH-loh-jist), which is a doctor with special training in blood disorders.

Disclosures

Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.

MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.
