EPFL, the Swiss Federal Institute of Technology in Lausanne, is one of the most dynamic university campuses in Europe and ranks among the top 20 universities worldwide. The EPFL employs more than 6,500 people supporting the three main missions of the institutions: education, research and innovation. The EPFL campus offers an exceptional working environment at the heart of a community of more than 18,500 people, including over 14,000 students and 4,000 researchers from more than 120 different countries

Mission

• Tree Acclimation and Mortality under Long-Term Heat and Drought Stress
• We are looking for a motivated technician to join the project “From Survival to Resilience: Acclimation as a Lifeline for European Forests under Climate Change”. This research is being conducted at WSL in Birmensdorf (Zurich), in collaboration with EPFL and INRAE, and focuses on understanding how long-term exposure to warming and drought influences the mechanisms underlying tree mortality and resilience
• The position will be based at WSL Birmensdorf, with occasional visits to EPFL during the summer. Most of the work will be conducted in the “Modoek” experimental facility, where beech and oak seedlings have been exposed to chronic warming and drought since 2019. The project aims to compare how acclimated trees die, focusing on trajectories, timing, and physiological thresholds

Main duties and responsibilities

• The technician will contribute to intensive monitoring of trees until mortality occurs. Key tasks will include:
• Measuring gas exchange and leaf water potential during stress progression
• Monitoring cell damage in plant tissues
• Sampling tissues to assess non-structural carbohydrate (NSC) dynamics
• Study environmental sciences, ecology, plant physiology, biology, environmental engineering, or a related field
• Enjoy fieldwork and teamwork
• Are motivated, rigorous, and curious about plant responses to climate extremes
• Have a driving license (helpful but not essential)
• Hands-on experience in forest ecophysiology and climate change research
• Training in ecophysiological measurements and field instrumentation
• Integration into an active, international research team at WSL and EPFL
• Opportunity to contribute to high-impact scientific publications
