  • I am a Professor of Medical Physics in the Department of Radiation Oncology at Loyola University Medical Center. I am interested in education, research and clinical activities that are aimed at cancer treatment with X-rays. My main focus is state of the art treatment machine: ViewRay MRIdian which uses Magnetic Resonance Imaging to precisely target cancer cells and adapt radiation treatments to anatomical changes caused by respiration, weight gain/loss etc.

    • BS, University of Delhi
    • PhD, University of Georgia
    • Fellowship: University of Minnesota Hospital and Clinics, Radiology

    What prompted you to pursue your field?

    I work in a field that combines my passion for physics and medicine with helping patients get the best care possible. I am also working with a multi-disciplinary team and involved with teaching and research.

    What's it like to teach at Parkinson?

    Through the Parkinson school's graduate program in Medical Physics, I will be helping train future medical physicists. We offer a program supported by a dedicated team of diverse and talented faculty and administration.

    Why is this area of study important at this point in time?

    Medical physics is an exciting discipline that is aimed at diagnosis and treatment of cancer. The field is at the forefront of computer and technological innovation.
