Main Research Areas

Physiology and biochemistry of microbial reductive dehalogenation of chlorinated phenols and chlorinated ethenes

Physiology and biochemistry of microbial degradation of glyphosate and AMPA

Assessment of transformation reactions of organic contaminants using compound specific (stable) isotope analysis: differentiation of reaction mechanisms and identification of rate-limiting steps

 

Current Research Activities

Combining molecular biological analyses (e.g. mRNA quantification) with CSIA to study stable isotope fractionation of chlorinated ethenes during expression of multiple reductive dehalogenases enzymes

Effect of microbial community composition on stable isotope fractionation of chlorinated ethenes

Application of CSIA to evaluate bioavailability restrictions during microbial degradation of glyphosate and AMPA
