Dr. Ikoma received his Master’s Degree in Public Health from The University of Texas School of Public Health. His clinical research interests include improving short and long-term treatment outcomes using minimally-invasive (robotic) surgery techniques for pancreas and gastric cancers. He has received multiple research awards from the Society of Surgical Oncology and the Japanese Surgical Society for his gastric cancer research. He is also interested in improving racial disparity to deliver high-quality cancer treatment equally to all patients, through his public health research. He is an active collaborator in translational research projects of localized treatment for pancreatic and bile duct tumors.
