- Albert Cheh received a BA in Chemistry from Columbia and a PhD in Biochemistry from UC Berkeley. His research focuses on the biochemistry of enzymatic digestion of biomass to produce cellulosic ethanol biofuel. He recently supervised two NIH postdocs studying error-prone bypass DNA polymerase action at polycyclic aromatic hydrocarbon diol epoxide (PAH-DE) induced damage sites, and has studied PAH-DE reactions with DNA, water chlorination mutagens and toxic heavy metals.
