Clinical Expertise

  • Gastrointestinal Cancers
  • Cancer Genetics (Familial Cancer Program)


Dr. Greenblatt's research interests are in interpreting genetic variants in cancer susceptibility genes by using multiple lines of evidence (epidemiology, statistics, tumor pathology, evolution, structure, and function, computational algorithms). He has led projects that have integrated in vitro and in silico (computational) data to interpret genetic variation. Dr. Greenblatt’s current research activities involve interpretation of variants in the DNA mismatch Repair genes that are responsible for Lynch syndrome, the most common form of hereditary colorectal cancer.
