Dr. Colin N. Waters is an Honorary Professor at the Geography, Geology and the Environment School, University of Leicester, and in 2019 was Visiting Professor at the University of Vienna. He is a retired principal mapping geologist, formerly working at the British Geological Survey for nearly 30 years. His main areas of research are Carboniferous and Anthropocene stratigraphy, which in the UK are combined with the formation of anthropogenic deposits in coal-rich industrial heartlands. His early interest in the Anthropocene related to mapping, characterizing, and quantifying these human-made deposits. Waters has been Secretary of the Anthropocene Working Group since 2011 and its Chair since 2020. This has led to broadening interest in assessment of the Anthropocene as a geological epoch, particularly in helping quantify its scale, the importance of specific markers for correlation (notably plutonium), and establishing the collaboration with HKW on the current GSSP assessment. He has around 150 peer-reviewed publications and was lead editor of A Stratigraphical basis for the Anthropocene, published by Geological Society, London, in 2014.
