About the projectThe Institute of Energy and Environment at the HES-SO Valais–Wallis is seeking a motivated PhD candidate to join the European project PRISE, focused on Positive Energy Districts (PEDs) and their role in climate-neutral cities.The research will combine technical modelling and social dimensions. On the technical side, the PhD will explore how to integrate energy vectors (electricity, heating/cooling, energy storage, renewables) and sustainable mobility options (active mobility, EVs, electrified public transport) to optimize PEDs under demand response and grid constraints. On the social side, the work will address governance and community engagement.The approach will be tested in Ostend (Belgium), with possible extension to Sion (Switzerland). The candidate will also contribute to:Mapping and characterizing PEDs across EuropeDeveloping taxonomies and data frameworksLinking modelling with stakeholder engagement and policyThis PhD offers a unique perspective on urban energy transitions, combining advanced modelling with interdisciplinary methods. The doctoral candidate will be enrolled at EPFL and jointly supervised by the HES-SO Valais–Wallis. Your profileWe are looking for a candidate with:A master’s degree in engineering or environmental sciences (energy, environmental, industrial, operations research, or related fields)A solid technical background and quantitative skills (experience with modelling, optimization, or data analysis is a plus)Coding experience in Python, Julia, MATLAB, or other high-level languagesOpenness to interdisciplinary research, bridging technical, economic, and social aspectsMotivation to engage with stakeholders and explore governance/policy questionsTeam spirit, intellectual curiosity, and the ability to work independently What we offerA position in a dynamic international research consortium at the forefront of the European energy transitionThe chance to collaborate with leading universities and research institutes across EuropeA unique opportunity to combine technical expertise with policy and social dimensionsA stimulating and supportive environment to develop your career as a researcher Employment: 100%Place of work: SionStarting date: no later thanContract duration: 1 year, renewable annually (total duration approx. 4 years) For further information or informal inquiries, please contact Prof. Jakob Rager at (α) or Dr Alejandro Pena-Bello at (α).
