Dr. Sahgal's primary focus is the use and evaluation of high dose per fraction radiotherapy delivered stereotactically to spinal tumors and evaluation of spinal cord late effects from high dose per fraction radiation. He also researches stereotactic radiotherapy and radiosurgery for eye and brain tumors.

Key areas of development:

1. Stereotactic body radiotherapy for spinal metastases


2. Guidelines for spinal cord tolerance with high dose per fraction radiation


3. Use of radiosurgery in multiple brain metastases


4. New radiation technology evaluation
