Biography

Dr. Rathan M. Subramaniam is an Associate Professor in the Johns Hopkins Medicine Division of Nuclear Medicine within the Department of Radiology and Radiological Science.

He also has appointments in the Department of Otolaryngology-Head and Neck Surgery and the Department of Oncology.

An internationally recognized expert in quantitative molecular imaging with positron emission tomography (PET) and computed tomography (CT), Dr. Subramaniam specializes in diagnostic radiology.

His clinical and research interests include molecular imaging in cancer, neuroimaging, and health policy and management.

Dr. Subramaniam earned his medical degree from Australia’s University of Melbourne Faculty of Medicine. He completed an internship at Melbourne’s Western Hospital, a radiology residency at New Zealand’s Waikato Hospital, and fellowships in nuclear radiology and neuroradiology at the Mayo Clinic.

A 2003 Fulbright Scholar, he also holds a Masters in Clinical Education from Australia’s University of New South Wales Teaching Hospital and a Ph.D. from the University of Auckland in New Zealand. In addition, he earned a Masters of Public Health from Harvard University and an executive certificate in leadership and management from the MIT Sloan school of Management.

Dr. Subramaniam was President of the Association of University Radiologists in 2013 and continues to serve in many capacities. He has delivered nearly 100 invited CME lectures and been awarded more than 20 research grants worldwide.

He has published nearly 80 peer-reviewed articles, co-edited Novel Imaging Techniques in Neurodegenerative and Movement Disorders, An Issue of PET Clinics, 1e (The Clinics: Radiology) and authored PET/CT and PET/MRI in Oncology: A Practical Guide.

A Fellow of the Royal Australian and New Zealand College of Radiologists, Dr. Subramaniam is American Board of Radiology-certified in neuroradiology and diagnostic radiology.
