ICREA Research Professor, Institute of Environmental Science & Technology, Universitat Autònoma de Barcelona (ICTA-UAB). Honorary Professor of Environmental & Resource Economics, School of Economics & Business and Institute for Environmental Studies, Vrije Universiteit Amsterdam (VUA). Head research group 'Environmental & Climate Economics' at ICTA-UAB. Previously Professor of Environmental Economics (1997-2007) at VUA, and editor-in-chief of the journal Environmental Innovation & Societal Transitions (2011-2021). He holds a Master degree in Econometrics & Operations Research from Tilburg University, and a PhD from VUA. He was awarded the Shell Sustainability Research Prize 2002 by the Royal Netherlands Academy of Arts and Sciences, IEC's ("Sant Jordi") Environmental Prize 2011, two ERC Advanced Grants (2017 & 2023), and an honorary doctorate from the Netherlands’ Open University (2019).

He works on the interface of environmental economics, climate-policy research, and innovation studies. Research in recent years focuses on effectiveness and public support of climate policy. This accounts for undesirable systemic impacts, such as energy rebound and carbon leakage, and the role of dynamic climate clubs of countries. It makes use of methods and insights from behavioural and evolutionary economics, operationalized through agent-based modelling, questionnaire surveys and online experiments. Past work covered integrated ecological-economic modelling, contributions to the growth-versus-environment debate, environmental policies applied to urban-transport issues, biodiversity valuation and policy, circular economy and recycling, and international aspects of environmental policy.
