Dr. Kathryn G. Logan is a Postdoctoral Research Fellow at the Arizona Institutes for Resilience as part of the University Climate Change Coalition (UC3) project to help identify and analyse novel pathways considering trade-offs, synergies, and equity as the City of Tucson develops their climate action plan. Prior to this, Dr Logan worked as an Energy Policy Researcher at University College Dublin, Ireland, investigating energy systems, energy management and energy in society for both academics and policymakers in Ireland. Dr Logan obtained both her BSc (Hons) and PhD degrees in Environmental Science from the University of Aberdeen, Scotland. Her PhD research investigated the impact of the electrification of transport and the related trade-offs between greenhouse gas emission reductions, climate regulation and the potential impact upon ecosystem services and natural capital. During Dr Logan's PhD research, she worked as a visiting researcher at Tsinghua University and Kyoto University doing case study analysis to better understand different methods of electric vehicle and train integration. Dr. Astley Hastings is a Reader in Environmental Science in the Institute of Biological and Environmental Sciences at the University of Aberdeen. He is a chartered engineer and environmental scientist, with a BSc in Mechanical Engineering and an MSc and PhD in Environmental Science. After 30 years of commercial experience, working in many senior capacities in the railway, power and oil and gas industries, Dr. Hastings conducts research into the greenhouse gas emissions, environmental impact and its mitigation from land use, low carbon energy and transport infrastructure. His work also focuses on greenhouse gas removal using afforestation and bioenergy carbon capture and storage and decommissioning and reuse of offshore energy assets and the impact on the environment. Professor John Nelson holds the Chair in Public Transport, Institute of Transport and Logistics Studies (ITLS), University of Sydney. He was previously the Sixth Century Chair of Transport Studies in the School of Engineering at the University of Aberdeen, UK, and Director of the Centre for Transport Research. John is particularly interested in the application and evaluation of new technologies to improve transport systems as well as the policy frameworks and regulatory regimes necessary to achieve sustainable mobility. He an Editorial Board member of several leading journals and co-author of Understanding Mobility as a Service (MaaS). Past, Present and Future (Elsevier, 2020), co-editor of Urban Form and Accessibility: Social, Economic, and Environment Impacts (Elsevier, 2020), and co-editor of The Routledge Handbook of Public Transport (2021).
