Research
As a fellow in the Marie Curie ITN, CSI:ENVIRONMENT project, I will investigate the variability of isotope fractionation during microbial degradation of halogenated organics, including chloro- and bromo-ethenes, ethanes, and benzenes. My research goals include: obtaining an understanding of how biotic degradation reactions cause isotope fractionation by molecular modeling of degradation reactions; determining the novel forensic isotope fingerprints of pollutants as produced by various manufacturers; determining fractionation factors (α D, C, Cl, and Br) during reductive dehalogenation and oxidation of chloro- and bromo-ethenes by designing reference fractionation experiments with microorganisms, cell suspensions, and enzymes under controlled conditions; developing microcosms from groundwater samples obtained from Bitterfeld and sediment samples obtained from Neuruppin to assess the variability of isotope fractionation during microbial degradation of brominated vs. chlorinated compounds; optimizing extraction, isolation and analysis procedures for chemicals in groundwater and sediment in preparation for isotope analysis; and developing multi-dimensional isotope models (D, 13C, Cl) to characterize degradation pathways and quantify degradation.
