Professor, Applied Health Sciences

Contact
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.
Education
- 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.
