Occupation:
Medical physicist specializing in diagnostic radiology

BORN:
Mysore, India, October 16, 1963

EDUCATION
B.Sc. in Physics, Electronics and Mathematics,University of Mysore, Mysore, India
M.Sc. in Solid State Physics, University of Mysore, Mysore, India
M.S.  in Physics, Marquette University, Milwaukee, WI
Ph.D. in Medical Physics-Biophysics, Medical College of Wisconsin, Milwaukee, WI.  

CERTIFICATIONS:

CAREER:
Dr Mahesh began his career in medical physics immediately upon completing his PhD in Wisconsin.  He joined Johns Hopkins Hospital as Chief Physicist in 1993.  He is currently an Assistant Professor of Radiology at Johns Hopkins University School of Medicine and the Chief Physicist at Johns Hopkins Hospital Baltimore, MD.  His research interests are in medical imaging, particularly in areas of multi-detector computed tomography (MDCT), interventional fluoroscopy and digital mammography. He is board certified from the American Board of Radiology in diagnostic radiological physics. He served as board member of the American Association of Physicists in Medicine (AAPM), and is a member of the Radiation Control Advisory Board for the State of Maryland and Scientific program committee member for the Radiological Society of North America. His editorial activities include, Contributing Editor for RadioGraphics, Editorial Advisory Panel Member for American Journal of Roentgenology (AJR), Editoral Board Member and Physics Column Co-Editor for Journal of American College of Radiology (JACR) and peer reviewer for a number of journals.  He is also the Editor for the AAPM Newsletter. He is a member of Scientific Committee at the National Council of Radiation Protection (NCRP) investigating especially on CT doses to the United States Population. He is also the Chair of the AAPM/RSNA Physics Tutorials, Chair of the Physics panel for ACR-Diagnostic X-ray In-Training examination and Chair of International Scientific Exchange Programs at AAPM.  Prior joining Hopkins, Dr Mahesh obtained his Ph.D. in Medical Physics from Wisconsin.  He has published and lectures extensively in the area of MDCT technology and other medical physics areas. Dr. Mahesh has been invited to be the UN-IAEA expert to participate in the IAEA activities and recently undertook UN assignment as IAEA expert and lecturer to the Radiation Protection for Cardiologists meeting in Bangkok, Thailand. Dr Mahesh also serves as a Scholar for Gerson Lehrman Group, an independent primary research firm serving business and investment leads in North America, Asia and Europe.
