Dr. Ghassan El-Haddad joined the faculty of Moffitt Cancer Center as an Assistant Member in the Interventional Radiology Section of the Diagnostic Imaging Department. Dr. El-Haddad earned his MD degree from Lebanese University. He completed a Nuclear Medicine Residency, Nuclear Oncology Fellowship and Pediatric Nuclear Medicine Fellowship at the Hospital of the University of Pennsylvania. He subsequently spent several years on the Penn faculty as an attending in the Nuclear Medicine section of the Department of Radiology. In 2011, Dr. El-Haddad completed a Radiology Residency at St. Vincent’s Medical Center/University of Connecticut where he served as chief resident. He most recently completed a Vascular and Interventional Radiology Fellowship at the Hospital of University of Pennsylvania. Dr. El-Haddad's clinical interests are to promote the role of individualized image-guided therapies as part of a multidisciplinary approach to provide the most effective treatment for patients with cancer while maintaining an optimal quality of life. His research interests include development of novel targeted and minimally invasive image-guided cancer therapies.
