I am a hematologist with a special expertise in vascular medicine. My main research interests within that field are venous thromboembolic disease and new anticoagulants. I have published a few journal articles on those topics, and in the future I will focus my efforts on the study of cancer-associated thrombosis. My clinical practice encompasses the whole spectrum of non-malignant blood conditions, including bleeding disorders and anemias. Lastly, I am involved in teaching medical students, residents, and fellows.
