Treatment Philosophy
I chose to join the Radiation Oncology faculty at Fox Chase after completing my training here because I believe that cancer is best treated in a multidisciplinary setting with the highest standard of clinical care. Here, cancer patients receive outstanding, compassionate treatment delivered with state of the art technology. I strive to maintain strong relationships with my patients and work with them to develop personalized treatment plans for their individual needs. I particularly enjoy our multi-disciplinary approach, as I feel that much more can be accomplished when people of different backgrounds and expertise work together on a common goal.
My primary treatment site is genitourinary malignancies, where I treat patients with both external beam radiation and brachytherapy. I am particularly interested in Prostate High Dose Rate (HDR) Brachytherapy which can reduce toxicity for certain patients while maintaining excellent cancer control. Prostate cancer has also been the focus of my academic interests and I have multiple active clinical and translational studies, including a national study comparing moderately-hypofractionated intensity modulated radiation therapy (IMRT) and proton radiation therapy.
After earning my Bachelor of Science in Chemical-Biological Engineering at the Massachusetts Institute of Technology and a Master’s of Engineering in Biomedical Engineering through the Harvard-MIT Division of Health Science and Technology, I attended medical school at the University of Tennessee. I believe the combination of my science and engineering background with my clinical training gives me a unique perspective to pursue clinical and translational research. Having a strong science background allows me to determine what scientific investigations are feasible and having a strong clinical background allows me to ensure that experiments are clinically relevant, allowing for the most immediate impact on patient care. I seek to further the understanding of radiation’s interaction with the body to improve treatment techniques and develop novel cancer treatments.
In addition to quality patient care and cutting-edge research, I also enjoy radiation oncology education and mentorship. I am active in the American Society for Radiation Oncology (ASTRO), Society of Women in Radiation Oncology (SWRO), American Brachytherapy Society (ABS), Association for Directors of Radiation Oncology Programs (ADROP), and Radiation Oncology Education Collaborative Study Group (ROECSG). I am proud to serve as the Assistant Director of our radiation oncology residency program and fellowship training program as our talented medical students, residents, and fellows are the future of our field.
