Profile
Andy's interests are in the importance of microbes in regulating many common chemical reactions at the Earth's surface and in the deep subsurface, specifically through the interaction with mineral surfaces. He is particularly interested in how such processes allow microorganisms to survive in cold and icy environments and potentially on other planets. Andy also undertakes applied research into manipulating these biogeochemical processes for environmental engineering purposes, including metal and radionuclide pacification and geologic carbon capture and storage. Before coming to Aberystwyth, he was at Montana State University where he was an Assistant Research Professor in the Faculty of Chemical and Biological Engineering. Prior to this, Andy was a EU Marie Curie Fellow at the NanoGeoScience Centre, University of Copenhagen, a Postdoctoral Fellow in the Department of Microbiology, Montana State University, and a Postdoctoral Fellow in the Department of Geology, University of Toronto. Andy has travelled and worked all over the world, and is particularly drawn to mountainous areas and mountain sports.
