Steve Rackley completed a PhD in Experimental Physics at the Cavendish Laboratory, University of Cambridge. Following a career spanning four decades in the energy industry, gaining experience in some of the main technologies that are key to geological carbon storage, he is currently a technical author, project consultant, and independent researcher into carbon capture and storage, and negative emissions technologies, with a particular interest in ocean based approaches.Prof. Tingzhen Ming joined Wuhan University of Technology in 2015 as a professor and served as Chair at Department of Built Environment and Energy Engineering since 2018. He graduated from Huazhong University of Science and Technology in 2007 with a PhD degree in Engineering Thermophysics. In 2003, Prof. Ming worked at Huazhong University of Science and Technology, later he worked at Nanyang Technological University, University of Florida, and University of North Texas. His expertise includes heat and mass transfer, renewable energy, energy and buildings, carbon neutral technology, and micro/nano heat transfer.Dr Wei Li joined the University of Edinburgh in 2021 as a Senior Lecturer in Chemical Engineering. He studied chemical engineering at the Nanjing University of Technology, obtaining his B.Eng. and Ph.D. in 2008. His first employment started at The University of Hong Kong (Department of Chemistry), followed by research positions at the Ludwig-Maximilians-Universität München (Department of Physics) and the University of Liverpool. Before he joined UoE, Dr Li also had worked at the National Graphene Institute, University of Manchester, and Aston University. His expertise includes nanoengineering of photocatalytic materials and reaction engineering of photocatalytic processes.Mike Tyka studied Biochemistry and Biotechnology at the University of Bristol. He obtained his PhD in Biophysics in 2007 and went on to work as a research fellow at the University of Washington and has been studying the structure and dynamics of protein molecules. In particular, he has been interested in protein folding and has been writing computer simulation software to better understand this fascinating process. Protein folding is the way our genetic code is interpreted from an abstract sequence of data into the functional enzymes and nano machines that drive our bodies. Mike currently works on machine learning at Google in Seattle.Dr. Adrienne Sewel completed a PhD at the University of Glasgow titled 'Crust atmosphere coupling and carbon sequestration on early Mars', where she was fortunate enough to visit sites such as the CARBFIX project discussed in this book. After her PhD she briefly lectured astrobiology at the University of St Andrews and robotics and mechatronics summer schools at the University of Glasgow. For the last few years she has been living on a boat exploring the waterways of France with my cat, chickens, and rabbit on board, occasionally writing science. She previously authored a chapter titled 'Mineral carbon sequestration' for the book Carbon Dioxide Utilisation published by De Gruyter in 2019.Diarmaid Clery is a Research Associate at the Tyndall Centre for Climate Change Research, where he has been since 2019, upon completing his PhD at the University of Leeds. The overall aim of his research is to understand the interdisciplinary issues related to tackling climate change, including decarbonisation and greenhouse gas removal (GGR). He has previously worked on assessing the feasibility of negative emissions for meeting climate targets. Currently, he is working with the CCUS clusters in the UK to assess the social licence for industrial decarbonisation.
