Research interests

  • Biogeochemical cycles in lacustrine ecosystems
  • Isotopic tracing in water reservoirs
  • Use of stable isotopes to monitor water reserves
  • Eutrophication processes and their effects on drinking water quality
  • Effects of anthropogenic activities on the isotopic composition of aquatic ecosystems
  • Impact of climate change on lake biogeochemistry

Get in touch

I am open to collaborations with scientists across disciplines.
Students looking for internships or seeking topics for their bachelor’s or master’s theses are welcome to connect and explore potential projects and ways to contribute to ongoing research.
