Alastair is a PhD candidate and former Lunar and Planetary Institute (LPI) Summer Intern. He is 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, 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. His ongoing collaborative research with LPI includes an investigation of deformational structures found in carbonaceous meteorites and the consequences for fluid transport.
