I am an interventional radiologist who specializes in interventional oncology, which uses imaging to guide minimally invasive cancer treatments. Interventional oncology is a rapidly advancing field in which we use cutting-edge technology to directly target cancer. I use many different imaging techniques to ensure precision and avoid complications. Most procedures I perform at Memorial Hospital in Manhattan are outpatient or require overnight stay, with minimal recovery time.

Most interventional oncology procedures I perform fall into two categories: arterial or ablative. Arterial procedures rely on a tumor’s circulatory system to deliver microscopic beads loaded with radioactive material or chemotherapy. Ablative therapies use energy to either heat or freeze tumors. I use these tools to treat primary and metastatic tumors in the liver, lung, and kidney, as well as skeletal and soft tissue tumors.

My clinical interest has focused on pain treatment and palliative care. For example, people with bone metastases can get pain relief through image-guided ablation or cement injections to reinforce the bone. My objective is to provide new strategies to improve quality of life at every stage of my patients’ cancer journeys.

Lymphatic interventions are a core aspect of my clinical research. I can access the lymphatic system with a tiny needle, which allows me to treat lymphatic leaks in a minimally invasive fashion.

Ultimately, my goal is to provide excellent patient-centered care through the assessment of each patient’s individual needs. I love working with my medical, surgical, and radiation oncology colleagues in order to provide a first-class experience for Memorial Sloan Kettering patients.
