Jonathan Cullen is the Professor of Sustainable Engineering at the University of Cambridge. He leads the Resource Efficiency Collective (www.refficiency.org) and has a reputation for top-down studies of resource systems, bringing skills in developing new metrics to reflect both energy and emissions consequences of materials production. Jonathan's research interests span energy and material systems, efficiency limits, circularity and zero carbon transition pathways. He currently leads C-THRU: carbon clarity in the global petrochemical supply chain (c-thru.org), and is a co-investigator on: CCG, TransFIRe: Foundation Industries Research and Innovation Hub (transfire-hub.org), S2uPPlant: Smart Sustainable Plastic Packaging from Plants (UKRI), and UK FIRES: Locating Resource Efficiency at the heart… [Read more]

Jen is a Research Fellow at the UCL Institute for Sustainable Resources, working across the CCG workstreams on System Design and Policies for CCG Investment. Her research covers techno-economic, social and environmental aspects of energy system transition pathways. She is currently working with partners in Zambia, developing methods to understand the drivers and impacts of land-use change, in particular related to bioenergy and other renewables. [Read more]

Naomi is the lead of the data and modelling tools business line within CCG. Alongside this, Naomi is currently completing her PhD focusing on the ‘Data-to-Deal’ analytical workflow.  This is a conceptualized framework for linking multiple open-source and open-access tools together from start to end. Using raw open-access data, the framework aims to bridge the gap between technical, social, and financial aspects, and provide results that can shape financial and political decisions within a country.   Having worked with SEforAll, IAEA, IEA, ADB and the UK COP26 Unit, Naomi is experienced in energy systems modelling and financial planning for sustainable… [Read more]

Tonny is a PhD researcher at Oxford University’s Smith School of Enterprise and Environment. He studies sustainable pathways for delivering affordable clean energy in low-income countries. Specifically, this involves investigating how different innovative approaches in business models and policies can accelerate the diffusion of renewable energy technologies and achieve multiple development goals. In CCG, Tonny is involved in projects ranging from developing data framework tools for investible energy business models, to climate adaptation entrepreneurship. [Read more]

Cath Ibbotson is the Programme Manager for Oxford Net Zero and is responsible for the day-to-day management of the initiative. Cath is a Chartered Engineer and comes to the University from industry where she has 15 years’ experience in the development of commercial-scale onshore wind farms. Her most recent role was as Director of a specialist independent development company, working with multi-national joint venture partners to deliver onshore wind energy projects throughout the UK. She is also a Director of a community owned onshore wind farm in the North West of England in a voluntary capacity. [Read more]

Mathias is a research assistant in Climate Compatible Growth at the Smith School of Enterprise and the Environment. His research, which focuses on the role of public and blended finance for climate resilience and adaptation, forms part of CCG’s work stream on Economics and Policy (WS5). He also contributes to the Resilience and Development research theme at the Environmental Change Institute and holds additional affiliations with Oxford Net Zero and the Institute of New Economic Thinking (INET) at the Oxford Martin School. His research interests lie at the intersection of environmental and development economics with a methodological focus on policy evaluation, microeconomic theory, inferential statistics, and spatial data. He is particularly… [Read more]

Roberto is a PhD candidate at KTH Royal Institute of Technology in Sweden, specializing in energy systems modelling and analysis. Roberto’s research focuses on energy system modelling,  integrating renewable energy sources, conventional power plants, storage systems, and demand-side management strategies. Roberto has engaged with CCG partner country Kenya to develop CLEWs models, among other projects in Goa (India), Indonesia, and Ecuador. Roberto has also worked in the Oil and Gas industry, designing production facilities in projects involving complex 3D modelling for two multinational companies based in Ecuador.   In addition to his academic career, Roberto has experience as a lecturer… [Read more]

Leonhard is a Research Fellow at the UCL Energy Institute and supports CCG's System Design activities. His research interest focuses on just transitions, as well as energy system modelling and its role in governing the transition to sustainable and equitable energy systems. [Read more]

Emma is a research assistant focusing on energy systems modelling. Her current work is on developing an interactive visualisation tool for the OSeMOSYS energy model. Following the 2050 Calculator concept, this will enable experts and non-experts alike to explore in real time a myriad of possible future energy pathways. Previously, she contributed to a variety of projects, including the OpTIMUS Community Summer Schools, Data-to-Deal and the Electricity Transition Playbook. Emma holds an MSc in Environmental Technology from Imperial College London, with a thesis applying OSeMOSYS to an LMIC. She also earned an MSci in Chemistry from the University of Surrey. [Read more]

Pietro Lubello is a Research Fellow at UCL Energy Institute, University College London, where he supports CCG’s System Design activities, mostly in Kenya. His research focus is on national and global energy models and the economic and social impacts of the energy transition. Pietro holds a PhD in energy system modelling from the University of Florence, Italy, where he worked on estimating the demand-side flexibility potential of the European residential sector.     [Read more]
