Professional biography

I am a PDRA in AstrobiologyOU and as geochemist I use thermochemical modelling to explore formation processes of alteration minerals that may occur as a result of the presence or absence of microbial life on Mars and on other planetary bodies. Secondary mineral assemblages predicted by thermochemical models can be used by astrobiologists as a bio-signature for the existence of life on extraterrestrial environments.

 

  • 2021 - present: Post-doctoral Research Associate at AstrobiologyOU - Thermochemical reaction pathway modelling of alteration phases under simulated Martian conditions.
  • 2020 - 2021 Post-doctoral Research Associate at The University of Manchester - Relationships between primordial and recycled noble gas in Icelandic plume.
  • 2020: Post-doctoral Research Associate at AstrobiologyOU - Modelling water-rock interactions in Martian environments.
  • 2019 - Ph.D. at The Open University - Noble Gas geochemistry and Ar/Ar geochronology.
