Research interests

Currently, I am scientific manager of the Research Unit Environmental Engineering and Biotechnology and support the Integrated Projects ‘Controlling Chemicals’ Fate’ and ‘Sustainable Biotechnology and Bioeconomy’.
My research in the Department of Isotope Biogeochemistry focused on the anaerobic biotransformation of halogenated organic contaminants and the application of stable isotope concepts. The main objectives of this research are 1) understanding of microbial transformation of chlorinated and brominated ethenes and ethanes, halogenated pesticides, e.g. hexachlorocyclohexane, and pharmaceuticals, e.g. diclofenac, and 2) development and application of multi-element compound-specific stable isotope (C, Cl, Br, H) fractionation as a tool to analyse microbial reactions and biotransformation in situ.


Projects

2011-2019 the DFG Forschergruppe "FOR1530 'Anaerobic Dehalogenation: Organisms, Biochemistry and (Eco-) Physiology'" links research groups in Jena, Halle and Leipzig. Within this project, I was in charge of sub-project 05: 'Characterisation of microbial dehalogenation using compound specific stable isotope analysis'.

Within the European Union FP7 project "GENESIS" we investigated how biogeochemical processes affect natural attenuation of chlorinated benzenes and are focusing on the microbial community involved in contaminant biotransformation.

From 2010-2015, I coordinated the European Union FP7 'People' programme Initial Training Network "CSI:ENVIRONMENT". In this project, 10 Partners and 4 Associated Partners from 9 European countries will work on 'Isotope forensics meets biogeochemistry - linking sources and sinks of organic contaminants by compound specific isotope investigation'.

2012-2014, Joint German-Israeli Water Technology Programme “Development of innovative tools for the assessment of in situ biodegradation of organobromine contaminant in groundwater” – INTIME. In this 3 year project we will investigate the application of CSIA for assessment of the natural attenuation of brominated groundwater contaminants.
