Fields of expertise
MissionThe mission of LRESE is to develop science and technology for efficient, inexpensive, sustainable, and durable approaches for renewable energy conversion. We focus on solar energy given its exceptional potential. The methodologies I promote incorporate coupled experimental-numerical approaches applying the fundamentals of thermal sciences, fluid dynamics, electro-magnetism, and thermo/electro/photo-chemistry in complex multi-phase/multi-component media on multiple scales. The research program I have established develops both theory and the computational frameworks in order to formulate design guidelines for complex multi-physics and multi-scale processes and devices, and applies and demonstrates these designs for photoelectrochemical and solar-thermal energy conversion and storage processes, enabling applications in other domains (e.g., space, environmental).
BiographySophia Haussener is an Associate Professor heading the Laboratory of Renewable Energy Science and Engineering at the Ecole Polytechnique Fédérale de Lausanne (EPFL). Her current research is focused on providing design guidelines for thermal, thermochemical, and photoelectrochemical energy conversion reactors through multi-physics modeling. Her research interests include: thermal sciences, fluid dynamics, charge transfer, electro-magnetism, and thermo/electro/photochemistry in complex multi-phase media on multiple scales. She received her MSc (2007) and PhD (2010) in Mechanical Engineering from ETH Zurich. Between 2011 and 2012, she was a postdoctoral researcher at the Joint Center of Artificial Photosynthesis (JCAP) and the Energy Environmental Technology Division of the Lawrence Berkeley National Laboratory (LBNL). She has published over 70 articles in peer-reviewed journals and conference proceedings. She has been awarded the ETH medal (2011), the Dimitris N. Chorafas Foundation award (2011), the ABB Forschungspreis (2012), the Prix Zonta (2015), the Global Change Award (2017), and the Raymond Viskanta Award (2019), and is a recipient of a Starting Grant of the Swiss National Science Foundation (2014). She is a deputy leader in the Swiss Competence Center for Energy Research (SCCER) on energy storage and acts as a Member of the Scientific Advisory Council of the Helmholtz Zentrum.
