I am broadly interested in the geological history of Solar System bodies and how life might have evolved on other planets and moons. I study microbes that live in the most extreme places on Earth such as the geysers and volcanoes of Iceland and red acidic rivers of Rio Tinto in Spain, as analogues for life we might find on other planets. I investigate how these microbes get trapped inside rocks and minerals, and how they can be identified using spectroscopy techniques, to help direct the search for life on Mars. I am particularly interested in, and involved in, developing techniques and technologies, such as IR capable microscopic imagers, for biomarker detection and developing the use of IR spectroscopy in astrobiological investigations. I am also involved with planetary analogue missions. Outside of my current experience, I am especially interested in studying organics within space materials and the prospects for life on Europa and Titan.
