My research interests centre around the oceans of ice-covered moons in the outer solar system, such as Europa and Ganymede (moons of Jupiter) and Enceladus and Titan (Saturn), which may be habitable today. I focus on how material delivered to the surface by 'cryovolcanism' can be used to learn about the oceans far below. My work involves experimental simulations of cryovolcanic processes and an array of spectroscopic, microscopic and geochemical techniques to track how ocean chemistry and even microorgansisms can be delivered to the surface. As a member of AstrobiologyOU, I make use of unique planetary surface simulation facilities to relate my findings to upcoming missions such as the JUpiter Icy Moons Explorer (ESA) and the Europa Clipper (NASA). Alongside my experimental work, I am involved in field analogue research in polar and sub-polar environments, including the Canadian High Arctic and Iceland.
