Dr Eva Llera is an Associate Professor in the field of Thermal Machines and Engines at the University of Zaragoza (Spain) and a member of the Energy and CO2 Research Group (http://energiayco2.unizar.es). Since 2016, she has also been the head of the "Energy and Environment" research group in the CIRCE Institute. Dr Llera holds a PhD in Industrial Engineering and a master’s degree in Eco-efficiency and Energy Markets from the University of Zaragoza. Her scientific career focuses on two parallel research lines. In the line of "Energy socioeconomics", she has participated as a multidisciplinary team member since 2007. In this area, she investigates jobs in renewables, energy poverty, and self-consumption adoption, contributing to the knowledge on the relationship between society, economy, and sustainable energy. She developed a methodology for employment assessment in the renewables and green sectors that was awarded by the Economic and Social Council of Aragon. In the research line of "Energy sustainability in activity sectors", she has participated in several projects focused on the search for new fuels and other measures for the improvement of efficiency and environmental impact reductions in energy-intensive industries such as cement, edification, or, currently, the aluminum industry. Energy analysis and LCA assessment have been applied in this line. Her main contribution is the multidisciplinary and integrated analysis of sustainable strategies in the transport sector.
