Research focus:
- Stable isotopes (C and N) for investigation of natural and anthropogenic factors with arsenic release processes in Bangladesh
- Geochemical studies on Arsenic release in Bangladesh with focus on anthropogenic impact factors (ponds, latrines, agriculture)
- Arsenic Mitigation Strategies in collaboration with AGAPE e.V. and the University of Dhaka, innovative water purification and piped water systems
- Arsenic remediation at industrial sites, using geochemical methods for enhanced arsenic release or immobilization of Arsenic
