Background

Dr. Mahadevappa Mahesh is a Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science and the Division of Cardiology. Dr. Mahesh also has a joint appointment in the Johns Hopkins Bloomberg School of Medicine Department of Environmental Health.

His research interests are in medical physics and imaging, particularly in areas of multiple-row detector computed tomography (MDCT), interventional fluoroscopy and digital mammography. He often provides counsel to patients concerned over their radiation exposure from diagnostic x-ray examinations.

He received a B.S. in math and physics and an M.S. in solid-state physics from the University of Mysore in Mysore India. He then completed an M.S. in physics at Marquette University in Milwaukee, Wisconsin, and in 1993 obtained his Ph.D. in medical physics from the Medical College of Wisconsin.

Dr. Mahesh is a fellow of the American Association of Physicists in Medicine, the American College of Radiology, the American College of Medical Physics and the Society of Cardiovascular Computed Tomography. He has authored numerous articles and a textbook in the area of MDCT technology and radiation doses in medical imaging, has lectured extensively in the U.S. and internationally, and serves on the editorial boards of several journals, including the Journal of the American College of Radiology, the Journal of the American Association of Physicists in Medicine, Academic Radiology, and RadioGraphics. He chairs or serves on numerous committees for professional organizations.
