Master theses or PhD?

We welcome applications for thesis projects (BSc or MSc) in physics, geology and/or another relevant disciplines within the natural sciences.  Salaries for PhD students and postdocs requires external funding, and candidates are encouraged to apply for their own grants. Vacant positions will be posted on KU’s website and here. Students in the Dahl lab do a combination of fieldwork, experimental work, and theoretical modelling within geobiology, biogeochemistry, geochemistry and Earth system science. Possible research projects are all linked to the origin and evolution of life and habitable environments on Earth or other planets:

  • Tracing oxygen and anoxia in ancient oceans and links to early animal ecology and biotic crisis (extinctions)
  • Reconstructing the history of atmospheric CO2 ans O2 levels
  • Predicting environmental impact of evolving animal and terrestrial ecosystems
  • Development and calibration of geochemical proxies (using novel tools, incl. synchrotron radiation, high-precision mass spectrometry, core-scanning XRF)
  • Trace metal geochemistry and cycling in modern environments
  • Bioessential trace elements for early life
  • Geoengineering (e.g. natural CO2 removal)

I also encourage students to develop their own research questions. Please contact me (tais.dahl at if you are interested in learning more about working in my lab.
