Jim Fredrickson

Dr. Fredrickson has focused his research efforts on the microbial ecology and biogeochemistry subsurface environments using geochemical and molecular approaches. These field research efforts, in combination with a multidisciplinary team, have led to defining the physical and geochemical properties and processes that control the composition and activities of microbial communities in the subsurface. More recently, Dr. Fredrickson has been investigating the geochemical and microbial factors that control the rate and extent of reduction and dissolution of Fe-oxides by dissimilatory iron-reducing bacteria. Integral to this research are investigations of the influence of these processes on the fate of inorganic contaminants including uranium and technetium.
