I’m a hematologist specializing in patients with T-cell lymphoma, T-cell leukemia, non-Hodgkin lymphoma, and allogenic and autologous stem cell transplantation. I received my medical training at Northeastern Ohio Universities College of Medicine, and I completed my residency at the Baylor College of Medicine. I then completed fellowships in hematology/oncology at Oregon Health and Sciences University and MD Anderson Cancer Center, where I spent a year as a faculty clinical researcher.

My research focuses on T-cell lymphoma and leukemia, as well as cellular therapy, including stem cell transplantation. I also serve as an assistant professor in Internal Medicine at The Ohio State University. My research has been published in numerous journals, including: Biology of Blood and Marrow Transplantation, Bone Marrow Transplantation and Leukemia and Lymphoma.

What I love about working at the OSUCCC – James is the collaboration between skilled medical professionals. The James fosters an environment that thrives on research, and working with such skilled colleagues makes me a better physician. I also love the opportunity to help my patients through one of the most difficult times in their lives. I believe that through research, cutting-edge technology and targeted care plans, we can work toward a cancer-free world and more hopeful outcomes for our patients.
