Alex's research combines molecular and biogeochemical approaches to determine microbial functionality and activity in the cryosphere. His previous research demonstrated that microbial activity at the surface of glaciers and ice sheets are responsible for significant carbon with implications for biogeochemical cycles at local and global scales. He is particularly interested in how the different actors in the ice microbial community (viruses, bacteria, fungi and algae) interact with each other and with their physical and chemical environment as part of the glacier and ice sheet biome.
