Biography

Alastair is an assistant lecturer and former Lunar and Planetary Institute (LPI) Summer Intern. His PhD thesis was on investigating chondritic meteorites as potential habitats for microorganisms on Earth and Mars. His training and academic interests include astrobiology, meteoritics and planetary geology.

Alastair uses electron microscopy, X-ray diffraction, computerised tomography, adsorption isotherms, and 16S rRNA sequencing to characterize the habitability microenvironments within meteorites and their microbial diversity. Alastair has also published on the topic of thermal metamorphism and silicate partial melting of parent bodies, and the discovery of structural controls within asteroid parent bodies on fluid transport. Currently Alastair has started new investigations into the role of microorganisms in minerlaisation of sediments in a unique hyper-saline sulfide-carbonate lake, as well as the micrometeorite flux of the early archean and the role it may have played on an early terrestrial biosphere.
