Dr. Arun Gopal completed his undergraduate studies in Mumbai, India before pursuing graduate degrees in Biomedical Engineering at the University of Tennessee and Nuclear and Radiological Engineering at the University of Florida. His graduate research work in megavoltage imaging physics eventually led to a strong interest in clinical medical physics. After completing a physics residency at the University of Florida, he worked as a medical physicist in New York Presbterian Hospital and Columbia University before joining the University of Maryland. His research interests include image guided radiotherapy and portal dosimetry, with strong clinical interests in surface guided radiotherapy, deformable image registration and image guided adaptive radiotherapy.
