Albert Cheh Prof Emeritus Environmental Science

by appointment
PhD, Biochemistry, University of California, Berkeley
BA, Chemistry, Columbia

My research focuses on signatures of exposure to environmental carcinogens. I have also studied the enzymatic digestion of biomass to produce cellulosic ethanol biofuel, error-prone bypass DNA polymerase action at polycyclic aromatic hydrocarbon diol epoxide (PAH-DE) induced damage sites, PAH-DE reactions with DNA, water chlorination mutagens and toxic heavy metals. I teach courses about our energy system and its relationship to climate change.
