Sarah Geneser PhD

Physics Residency Program

Inspiration: Challenge (both academic and athletic), compassion, and a constant drive for improvement.

Area of interest:(1) Developing more efficient and accurate treatment delivery methods for tumors that undergo organ deformation during or between treatment (e.g. respiratory motion, weight loss/gain, re-plans, salvage cases, secondary radiation treatments), (2) Assessing errors introduced into the treatment planning workflow by image registration methods, and developing registration methods that more accurately infer organ deformation from medical images, and (3) Developing novel radiation delivery methods that better leverage linear accelerator hardware capabilities to offer to improve patient outcomes.
