The research focus of the Simpson Lab is on the use of non-invasive bioimaging markers in oncology and incorporation of novel imaging modalities into radiation treatment planning. A primary research project is designed to evaluate the diagnostic accuracy of restricted spectrum imaging (RSI), a novel MRI diffusion technique, for presurgical assessment of treatment response in patients undergoing neoadjuvant radiation therapy for rectal cancer. As the principal investigator of this project, Dr. Simpson has assembled a multi-disciplinary investigative team with expertise in diagnostic radiology, colorectal surgery, radiation oncology, medical oncology, and pathology. 


 The ultimate goal of this research is to improve our understanding of in vivo tumor responses and to help to direct cancer therapy at an individual level.
