Biography
Christina Bremer is a Research Associate in the Cambridge Sustainable Computing Lab. She is working on the Green Algorithms Initiative, a project that focuses on quantifying and reducing the environmental impacts of computational science. As part of the project, she is studying the effectiveness of carbon reporting tools, such as carbon calculators, in incentivising more sustainable computing practices.
Before moving to Cambridge, she completed her PhD and first postdoc in the Socio-Digital Sustainability group at Lancaster University. Reflecting her background in human-computer interaction (HCI), her PhD research explored the energy-saving potential of digital behaviour change and efficiency interventions, taking into account technical factors, user behaviour, and rebound effects. After her PhD, she stayed in Lancaster to work on Net0Insights, a multidisciplinary project to design and develop data science tools that reduce commercial energy demand.
Christina is a Postdoctoral Affiliate at Newnham College, University of Cambridge, a 2026 Fellow of the Software Sustainability Institute (SSI), an Associate Fellow of Advance HE, and a member of the Research Coordination Network on the Digital Economy and the Environment (RCN-DEE). Initially, she received a BSc (Hons) Cognitive Science from the University of Edinburgh and an MSSc Human-Computer Interaction from Uppsala University.
Research
My research is situated at the intersection of society, digital technologies and environmental sustainability, spanning the fields of sustainable computing and sustainable human-computer interaction (HCI). Its aims are to limit the environmental impacts of computing technology and use computing to facilitate pro-environmental behaviours.
