Professor Marios Giannakis

Marios is a physician-scientist at the Dana-Farber Cancer Institute and Assistant Professor of Medicine at Harvard Medical School. He received his Honors Bachelor of Science degree in Molecular Biology and Molecular Genetics from the University of Toronto and his M.D./Ph.D. in Molecular Genetics and Genomics at Washington University School of Medicine in Saint Louis. He was a medical resident at Brigham and Women’s Hospital in Boston, a postdoctoral researcher at the Broad Institute of MIT and Harvard and hematology-oncology fellow at the Dana-Farber Cancer Institute.

Marios has an active clinic caring for patients with gastrointestinal cancers and his laboratory studies the genomics, immunogenomics, molecular epidemiology and tumor microenvironment of colorectal cancer using patient-derived biospecimens and pre-clinical models. His research aims to identify and characterize novel oncogenic drivers, elucidate the molecular, microbial and metabolic determinants of cancer immune infiltration and resistance, and lead to early-phase clinical trials for patients with colorectal cancer.
