Resident Research

Radiation Medicine Resident Research collage

Our program has a broad and flexible research focus that includes health services and outcomes-based research, clinical and translational research, as well as basic science research opportunities within OHSU community. Our goal is to provide an opportunity to garner a meaningful research experience during the critical years of residency training. 

Residents are encouraged to concurrently enroll into the Human Investigations Program (HIP), a training component within the institutional CTSA, also known as the Oregon Clinical and Translational Research InstituteEnroll in the Masters of Clinical Research Track or the Certificate Track. The residency is structured so concurrent participating in research activities are conducted such that all ACGME and ABR requirements are met. The length of the training program is not altered with research endeavors.

Clinical and Imaging Informatics

Current research

My research focuses on the application of clinical and imaging informatics (radiomics) to improve prediction of treatment response and radiation toxicities. Also, potential applications of artificial intelligence in the radiation oncology clinical workflow. Current projects include evaluation of auto segmentation algorithms of genitourinary structures and reviewing institutional outcomes following radiotherapy in the pediatric population.

Radiation induced oxidative stress by targeting metabolism of glioblastoma multiforme (GBM) 

Current research

I am interested in conducting metabolomic studies (the study of the metabolome, coined as an analogy with the genome, proteome, etc.), in vitro and in vivo, using various types of cell cultures and perfused organs in the context of radiation induced oxidative stress. The advent of molecular biology has allowed scientists to make progress in genomic and proteomic studies, however, in isolation, these approaches cannot complete our understanding of the complex mechanism underlying many human diseases. Metabolomics seeks to characterize the small-molecule metabolite profile of a cell, in order to provide biochemical fingerprint related to specific cellular processes. Critical information gathered from this emerging field of research can provide new insight into complex diseases like cancer, auto-immune disorders, and metabolic syndrome, each of which exhibits hallmark metabolic signature and symptomatology. Metabolomic studies, in conjunction with genomics, transcriptomics, and proteomics, will help complete our understanding of the systems biology underlying human disease.

I am also interested in using ketogenic diet and ascorbic acid as safe and effective radiosensitizer. These are current clinical studies at the University of Iowa.
