Raja Narayan, MD, MPH


I am studying prognostic patterns from digitally analyzed histology and radigenomics to guide perioperative therapy of colorectal cancer metastatic to the liver. I also am studying genomic data from gallbladder cancer specimen to predict disease patterns. I completed my undergraduate studies in Chemical Biology at Berkeley and an MPH in Biostatistics from Yale. I obtained my medical degree from the University of California in Irvine and have completed 2 years of residency training at Stanford in General Surgery.
