Alex Krause


I am a geochemist and biogeochemical modeller, working to address some of the major questions regarding the state of the Earth system during the Neoproterozoic and early Phanerozoic, particularly with regard to the evolution of atmospheric oxygen levels during this time. 

Prior to this I had a career within academic book publishing (Routledge, McGraw-Hill, CIPD Publishing), where I got to attend many conferences such as ISBE, EIBA and BAM as an exhibitor. I also worked part-time within the NHS, while I completed my MSc.

Research interests


I am interested in the biogeochemical evolution of the Earth system over time and the various factors which may have played a part in driving the Earth to its current state, and will continue to exert an influence far into Earth's future. I am also interested in building an understanding of how and why Earth became habitable and investigating habitability limits in the future, in order to use Earth as an analogue for planetary habitability in general.

I am funded by the Leeds-York NERC doctoral training partnership.


I currently (2018-19) assist with:

  • The MATLAB modelling workshops for the module: Earth System Science: Biogeochemical Cycles SOEE3110
  • The Daisyworld modelling workshop for the module: Environmental Change: Past and Future GEOG1055
  • Tutorials and labs for the module: Introductory Chemistry for Earth and Environmental Scientists SOEE1131
  • Practicals for the module: Chemistry of the Earth SOEE2010


I am a student member of the following organisations:

  • European Association of Geochemistry
  • The Geochemical Society
  • Astrobiology Society of Britain


  • PhD Student in Earth Science (2016 - Present)
  • MSc, Environmental Science, University of East Anglia
  • Graduate Certificate in Geology, Birkbeck, University of London
  • BSc, Physics and Meteorology, University of Reading

Research groups and institutes
