Biography

To err is human though no more than her unrelenting pursuit of excellence or his insatiable ability to improvise.

 

I joined as a research fellow in the Department of Radiology, Massachusetts General Hospital in 2001. During the fellowship, I was assigned to work on CT technology assessment and CT radiation dose reduction. From 2005 to early 2006, I was at the Emory University Hospital in Atlanta, Georgia as an Assistant Professor of Radiology and the Director of CT Research. I returned to MGH to pursue clinical fellowships in the Division of Thoracic Imaging and Division of Cardiovascular Imaging from 2006 through 2008. I joined as an attending radiologist in these divisions in late 2008 and was appointed as Instructor in Radiology with the Harvard Medical School. I was promoted to Assistant Professor in 2010 and then to Associate Professor of Radiology in 2012.

As a clinical expert and innovator, I have led to impressive repertoire of positive changes in CT protocols and CT radiation dose reduction for which I have received several institutional awards including multiple Partners in Excellence, Radiology Innovation Awards, and the Patient Safety Star.

I am a well published author in the field of CT radiation dose optimization with numerous original research and review articles in the top specialty journals in radiology including the journals Radiology, American Journal of Roentgenology, European Radiology, European Journal of Radiology, Journal of Computed Assisted Tomography, Investigative Radiology, Academic Radiology, Medical Physics, and Journal of Thoracic Imaging. I have also participated in projects and reports from the International Council for Radiation Protection (ICRP) as well as the International Atomic Energy Agency (IAEA), which represent some of the most reputed international organization in field of radiation dose. I am well-recognized nationally and internationally for my groundbreaking clinical innovations and research in CT radiation dose optimization.

I also serve as the Director of MGH Webster Center for Quality and Safety which was founded to enhance research and education in the field of radiation protection and later expanded to include all aspects of patient safety in radiology. As its director, I am responsible for mentoring several research fellows on projects related to radiation dose optimization and patient safety, organizing of teaching sessions, directing visiting fellowship program in radiation protection for radiologists and technologists, online educational content (in partnership with the International Atomic Energy Agency (IAEA), Vienna, Austria, and the Center for Medical Image sciences and Visualization (CMIV), Linkoping University, Sweden) as well as website content development. I also serve as the host and director of educational program at the MGH on radiation protection for visiting radiology personnel from developing nations (supported by the International Atomic Energy Agency). I serve on the editorial boards of several radiology journals and as a member of the National Council for Radiation Protection (NCRP), the Partners Healthcare Institutional Review Board (IRB), the RSNA Scientific Program Committee (Chest track) and the American College of Radiology Dose Index Registry (ACR DIR). 

In the past 15 years, I have published more than 170 original research and review articles (h-index of 51 with 10,567 citations, i10 of 144) and 30 book chapters, with most publications being on CT radiation dose optimization. In addition, I have edited three textbooks on CT including one of the most comprehensive textbook (Radiation Dose from Multidetector CT) specifically on CT radiation dose optimization. I have served as the primary/senior author, and/or the principal investigator for >95% of my publications in the field of CT radiation dose and protocol optimization.
