Dr André Cabrera Serrenho is an Assistant Professor and University Lecturer in Engineering, Environment and Sustainable Development at the University of Cambridge. His research explores new ways of reducing greenhouse gas emissions at a faster pace to meet international climate pledges. This involves identifying new configurations of energy and material systems to supply our future needs with less demand and emissions. André has been involved in the development of exergy-based analysis of national energy systems and new characterizations of material stocks to allow exploration of efficient material service provision. He has been working on the identification of opportunities for energy and material demand reduction in industrial systems. He developed dynamic material flow analyses to assess the stocks of cars, buildings, and plastics in the UK, testing the impact of alternative interventions to reduce global greenhouse gas emissions.
