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.
