Adrian Friday is Professor of Computing and Sustainability at Lancaster University, UK. My work focuses on how ubiquitous systems, data and empirical studies reveal the environmental and energy impacts of everyday life, and offer new and more sustainable ways of doing. I am passionate about understanding the relationship between the digital and the future, and how to promote sustainability. My collaborative and multidisciplinary projects in this area have focused on various sites of energy demand aligned with ‘digital futures’. These have included energy use in the home, thermal comfort, sustainable food shopping (‘rich and healthy life’); and understanding last-mile logistics to promote sustainability (‘smart society’). My ongoing projects are focusing on environmental and social justice for gig economy, and a significant new research programme exploring a combined statistical, machine learning and qualitative approaches toward net zero from energy and IoT data, co-designed with commercial stakeholders.
