Faculty

Division of Hematology and Oncology

Faculty of the Division of Hematology and Oncology are dedicated to the medical treatment and care of adults with cancer. Many of our faculty are involved in "translational research," meaning they conduct research studies, enabling many new treatments to be available as soon as they are approved for use. Several of our faculty members also teach in our medical school. We believe this combination of research, education and clinical treatment helps ensure that care provided is on the cutting edge.

To learn more about our faculty, follow the links below to access their Georgetown University faculty profiles. (If a particular faculty member doesn't have a link, their profile is currently under development and will be available shortly).
