He serves on the Editorial board of Annals of Surgical Oncology, Section of Gastrointestinal Oncology and PLOS ONE. His clinical research is focused on treatment outcomes in GI cancers. His laboratory research collaboration focuses on developing personalized approaches to targeted therapy for gastrointestinal malignancies and the role of the tumor microenvironment in tumor growth and metastasis.

Dr. Hanna is a Fellow of the American College of Surgeons and the Society of Surgical Oncology. He is a member of the Society of University Surgeons, the American Society of Clinical Oncology, and the American Academy on Communications in Healthcare. He is currently the Chair of the International Relationship Committee of the ACS and the Treasurer of the Maryland Chapter of the ACS.

Research Interests

Clinical Research

The focus of my clinical research includes population studies of treatment outcomes in GI malignancies, development of a post-operative clinical care pathway following major gastrointestinal cancer surgery; identifying predictors of recurrence and survival in patients undergoing CRS and HIPEC, identification of factors that correlate with post-operative outcome and complications following CRS and HIPEC.

Laboratory Research

Even though I currently have no independent laboratory, I continue to actively collaborate with several scientist both within the University of Maryland, other universities and the NIH. The focus of my laboratory research collaboration includes developing a personalized approach to targeted therapy for gastrointestinal malignancies and the role of the tumor microenvironment in tumor growth and metastasis.
