Marie Robert, MD

Pathology, Anatomic Pathology, Gastroenterology


Marie Robert, MD, is a surgical pathologist specializing in diagnosing gastrointestinal, liver and pancreatic diseases. Her interest in this area was founded in childhood during visits to her father’s lab where he studied mechanisms of gastrointestinal diseases. “My father’s passion for his work was infectious, instilling a desire to understand why illness happens at a cellular level.” During her pathology courses in medical school, Dr. Robert remembers looking through the microscope at tissue specimens and immediately becoming hooked. 

As a gastrointestinal pathologist at Yale Medicine, Dr. Robert examines hundreds of biopsies and surgically removed samples under the microscope each week, determining the diagnosis that will direct further therapy and predict the clinical outcome for each patient. “Pathologists provide crucial, life altering answers for patients,” Dr. Robert says. “Our job is a key component of the patient’s treatment and care. Even though the patient may never meet us, we have a significant impact on their life.”

A professor of pathology at Yale School of Medicine, Dr. Robert performs research on clinically relevant aspects of cancer immunotherapy, the diagnosis and management of celiac disease, and the molecular underpinnings of liver diseases and liver cancer. She is the lead pathologist for clinical, translational and basic science experiments on pancreas cancer at Yale Medicine.
