Peter T. Campbell, MSc, PhD

Scientific Director, Population Science

At ACS since 2008

Peter Campbell, MSc, PhD, is a scientific director in the Department of Population Science at the American Cancer Society (ACS). He primarily leads the gastrointestinal tract cancer epidemiology research at ACS, using internal resources (e.g., Cancer Prevention Studies (CPS) II and CPS 3 and their respective biorepositories) and in various large, international groups collaborations.

Campbell is also an adjunct Professor in the Rollins School of Public Health and the Winship Cancer Institute, both at Emory University.

Research Focus and Accomplishments

Campbell is particularly interested in understanding the role of obesity, physical inactivity, diabetes, and other potentially modifiable factors with gastrointestinal tract cancer etiology and survival.

He oversees the Cancer Prevention Studies’ colorectal cancer tissue repositories, and much of his work is at the intersections of pathology, molecular biology, genetics, and clinical medicine. His research involves consortia of study data and biologic specimens from hundreds of thousands of study participants, utilizes leading ‘omics’ and high-throughput technologies, and employs novel statistical techniques.

The overarching goal of his research is to better understand why some lifestyle/behavioral factors influence cancer risk or prognosis with a view to better inform and support the primary prevention of cancer and the care of cancer patients.
