Dr. Joséphine Broussin
I am a postdoctoral researcher in marine ecology, specialized in data analysis and marine Species Distribution Models (SDM). I have just completed my PhD, which focused on ecological realism in SDM by creating ecological pseudo-absences and integrating dynamic prey-predator relationship. I am now working with the group on fish biodiversity assessment at global scale, with an interest on its coastal-offshore gradient and the consideration of prey-predator interactions and fishes’s traits.
Dr. Nathan Beech
I am a postdoctoral researcher specializing in climate modelling with a focus on mesoscale ocean processes and climate change. Before joining the environmental physics group at ETH Zürich, I carried out my doctoral research at the Alfred Wegener Institute in Bremerhaven, Germany, where I used the ocean model external page FESOM to investigate the impacts of climate change on ocean eddies. At ETHZ, I will work within the EXCLAIM project using the atmosphere-ocean model external page ICON to conduct more high-resolution simulations of the climate and climate change.

Dr. Alexandre Schickele
I am a postdoctoral researcher at ETH Zürich, in the Environmental Physics group since 2023. Trained as a fishery scientist, my current research interests concern marine quantitative ecology and how environmental conditions shape plankton biogeography. Using a broad range of machine learning techniques and cutting-edge in-situ observations such as metagenomics, I investigate the complexity of plankton diversity and its relation to key ecosystem functions at the global scale. I also develop open access habitat modeling tools to produce high quality and standardized diversity products from the latest available plankton in-situ observations.
Dr. Aaron Wienkers
I am a postdoctoral researcher in the ETH Zürich Environmental Physics group. Zooming out from my PhD research on submesoscale ocean physics (at 0.1km – 10 km), I am now part of the external page EERIE project pushing forward our understanding of mesoscale dynamics in the ocean (c. 10 – 100 km). Together with the EXCLAIM project at ETH, we are leveraging the coupled climate model external page ICON at extremely high-resolution to probe the «weather» of the ocean. In particular, I am studying eddies — the vortical structures dominating this mesoscale «weather» — and their broader impact on the Southern Ocean, and ultimately the global climate

Dr. Jens Daniel Müller
I’m a biogeochemist studying the ocean carbon cycle through measurements of CO2 in seawater. Since 2020, I’m working as a PostDoc in the UP group at ETH Zurich. We use global ship‑based observations to reconstruct the accumulation of CO2 in the global ocean, and how this drives acidification in the ocean interior. This work profits from the experience gained during my PhD, specifically the development of pH analytics, the analysis of autonomous pCO2 measurements from a voluntary observing ship and several months spent at sea. As a coordinator of RECCAP2 ‑ the second cycle of the REgional Carbon Cycle Assessment and Processes project ‑ I’m working with an international board of around 100 scientists covering a broad view on the ocean carbon sink through models and surface flux estimates.
