Research Overview:

Dr. Buas’ primary research focus is the molecular/genetic epidemiology of esophageal adenocarcinoma (EA), and the development of novel approaches for cancer risk assessment, early diagnosis, and prevention. His active research includes basic etiologic studies of genetic susceptibility to EA and its precursor, Barrett’s esophagus (BE); applied biomarker discovery studies of circulating nucleic acids and metabolites linked to high-risk BE and early-stage EA; and integrative risk modeling studies aimed at combining genetic and non-genetic factors into robust predictors of absolute cancer risk. The long-term translational goal of this work is to synthesize improved clinical tools for enabling targeted prevention or timely interception of EA among at-risk individuals.
