Originally from India, Dr. Ramakrishnan received his initial medical training at the Medical College University of Kerala, India. He completed internal medicine residency training at the Jawaharlal Institute of Medical Education and Research in Puducherry, India. Drawn by the opportunity for the integration of clinical medicine, hematologic malignancies, and stem cell transplantation, he completed advanced training in hematology and medical oncology at the Thomas Jefferson University Hospital in Philadelphia, Pennsylvania, where he also earned a master's degree in pharmacology through the NIH K30 Training Program in Human Investigation.

Certified by the American Board of Internal Medicine in internal medicine and in hematology and medical oncology, he joined the UT Southwestern faculty in 2017.

Dr. Ramakrishnan's research interests include developing targeted and cellular therapies for treating patients with lymphomas.

Dr. Ramakrishnan is an active member of several professional organizations, including the American College of Physicians, American Medical Association, American Society of Clinical Oncology, American Society of Hematology, American Society for Blood and Marrow Transplantation, American Association for Cancer Research, American Association for the Advancement of Science, and the International Primary CNS Lymphoma Collaborative Group.

Personal Note

Outside of medicine, Dr. Ramakrishnan enjoys reading, watching movies, traveling, and quizzing. During his residency training, he was a three-time national champion at the American College of Physicians' Doctor's Dilemma competition.
