Meret Aeppli joined EPFL as a tenure track assistant professor and head of the soil biogeochemistry laboratory (SOIL) in September 2022. Her group aims to elucidate the fundamental principles and mechanisms of electron transfer reactions and their role in the biogeochemical cycling of carbon and metals in soil. Meret was a postdoctoral fellow at Stanford University in the department of Earth System Science from 2019 to 2022 where she studied biogeochemical controls on carbon turnover in soils and sediments. She holds a Bachelor's and a Master's degree in Environmental Sciences from ETH Zurich and obtained her PhD from ETH Zurich in 2018. She was awarded the ETH Medal for her dissertation work in which she developed novel approaches to quantify the redox properties and reactivities of iron minerals.
