new options to treat patients with metastasis. He has over 100 publications in the area of cancer biology and therapy. In
2013, Dr. Khanna transitioned his work at National Cancer Institute to that of a Strategy and Research Consultant with the
Center of Cancer Research.
As a bridge between his work as a clinician and clinician-scientist, he founded Animal Clinical Investigation, which is a

Dr. Bridget Stewart graduated from Bucknell University with a BS in Biology and from the University of Pennsylvania
Veterinary School with a VMD. She completed a small animal medical and surgical internship with Veterinary Referral
Associates in Maryland and then worked as an emergency clinician. During her internship, she performed a study on
emergency radiation therapy for dogs with urinary obstruction due to bladder and prostatic tumors, which she presented at
the Veterinary Cancer Society conference in 2005. Subsequent to this, she began working with the medical and radiation
oncology departments, and discovered her passion. In 2006, she left emergency medicine to work full time as an oncology
hospitalist. Dr. Stewart joined The Oncology Service in 2011 to assist with the opening of the TOS-Richmond clinic and
moved to the Springfield clinic in July 2013.

examination. In 2008, he moved to the Washington, DC area where he undertook advanced training as a postdoctoral
fellow in the Radiation Oncology Branch of the National Cancer Institute. His primary clinical interests include the use of
advanced imaging and radiation delivery techniques to improve tumor control and patient quality of life.
Dr. Gordon has a special interest in tumors of the head and neck and in tumors of the central nervous system. Dr. Gordon’
s research interests include the identification and investigation of drugs that increase tumor responsiveness to radiation or
improve the tolerance of normal tissues to radiotherapy. He has published primary research and review articles on these
subjects and has spoken at national meetings on these topics. He has received multiple awards for his work as a clinician
and clinician-scientist, including the George H. Hart Research Grant, Myrtle L. Oliver Memorial Resident Research Award,
