Board Certifications

Diagnostic Radiology; CAQ in Vascular and Interventional Radiology

As an interventional radiologist, I perform minimally invasive image-guided procedures using x-ray, CT scan, ultrasound, PET scan, and MRI technologies. These procedures include percutaneous biopsy, venous access (such as mediport placement), arterial embolization, and thermal ablation. As a doctor at Memorial Sloan Kettering, my primary responsibility is to provide excellent, safe, and compassionate care for my patients who are living with cancer, or who may be facing a cancer diagnosis.

My clinical interests include inferior vena cava (IVC) filter placement and removal, and interventional management of pelvic vein compression and leg swelling in people with cancer (including catheter-directed treatment of deep venous thrombosis). I am currently a site principal investigator of a national multicenter study evaluating the safety and effectiveness of IVC filters (PRESERVE Trial). 

Originally from Far Hills, New Jersey, I graduated magna cum laude from Duke University in 1998 with a BS degree in biology.  I attended Jefferson Medical College, and graduated as a member of the AOA Honor Medical Society in 2002.  I completed residency in diagnostic radiology  in 2009 at Mount Sinai Medical Center in New York City,  followed by a clinical fellowship in vascular and interventional radiology.

I am a board certified radiologist with subspecialty certification (CAQ) in vascular and interventional radiology from the American Board of Radiology.
