My research interests are broad, and I combine concepts from Geography, Biology and Chemistry to understand carbon cycle in the cryosphere. My research has concentrated in two broad areas. Firstly, I study microbes in the cryosphere. Against all expectations glaciers harbour a highly active microbial community. Bacteria, viruses and microscopic plants thrive in conditions that might be analogous to other planets and to early Earth. Second, I am also interested in a range of climate (e.g., UV radiation and acid rain) and human impacts (e.g., mining, sewage, pesticides) on freshwaters.


Alex is a Professor of Biogeochemistry in the Bristol Glaciology Centre at the University of Bristol. He gained his PhD in Limnology from Lund University, Sweden in 2000. His 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 and nitrogen fixation with implications for biogeochemical cycles at local and global scales. He is one of the advocates that glaciers and ice sheets are one of the biomes of Earth. He is author in over 65 peer-reviewed papers and has previously secured funding as PI from NERC, The Royal Society, The Leverhulme Trust and The Nuffield Foundation. Recently, he is also the coordinator of an Innovative Training Network, which includes 13 beneficiaries and 15 PhD students (H2020-MSCA-ITN-2015) with funding from the EU for investigating microbial communities and processes in the Arctic.
