My research involves clinical trials using radiotherapy in client owned pet dogs with spontaneous tumors. These spontaneous tumors in dogs have similar biological behavior as their counterparts in humans. Information obtained from these clinical trials help advance and inform the design of future trials in humans. My collaborative work with medical physicist colleagues is advancing knowledge and utilization of molecular imaging in the form of positron emission tomography (PET) to design individual radiotherapy plans.
My research experience includes being a project leader on a previous grant investigating the conformal avoidance capabilities of Helical Tomotherapy: CA88960-05 (Mehta PI) Improving Cancer Outcome with Adaptive Helical Tomotherapy: Animal Clinical Trial of Conformal Avoidance: Dog Nasopharynx. I am currently a Co-I on a grant investigating molecular imaging as a basis for individualized radiotherapy: NIH-144-PRJ26QD (Jeraj PI): Dose Painting Based on Hypoxia and Proliferative Response.

My main focus is radiation therapy in companion animals using our newly installed (January 2011) TomoTherapy machine. This is a state of the art radiation therapy machine that is the marriage of a linear accelerator and a helical computed tomography (CT) scanner. We are able to deliver precise, highly conformal treatments that target tumors and spare adjacent normal tissues and organs.
My other clinical interests include CT, magnetic resonance imaging (MRI), and general radiography.
