Research interests

I have a PhD from the National Polytechnic Institute of Toulouse in France, where I was working at the Snow Research Center of Meteo-france. During my PhD, I studied the impacts of the snowpack properties on microwave signal in mountainous areas.

I joined the British Antarctic Survey during June 2019 as a sea ice physicist. I’m now part of the Eco-Light program which purpose is to improve the understanding of how the changes in the Arctic physical environment (snow, sea ice and ocean) affect the large-scale ecosystem functioning of the Arctic marine environment. To do that, various science fields are brought together as well as modelling and observational expertise from United Kingdom, Germany, South Korea and Canada.

In this project, I’m focusing on the light behaviour in snow and sea ice (considering sea ice properties and thickness changes) and its impact on the biology.

1. Creating Standards for Climate Experiments

   Eco-ICE studies whether making Arctic sea ice thicker could harm ocean life and creates tools to help decision-makers work out if climate projects are safe.

2. Tracking Antarctica’s Ice Fluctuations

   The recent extreme swings in Antarctic sea ice extent emphasise the need to increase our knowledge of the drivers and climate implications of Antarctic sea ice loss.

1. Retreating sea ice keeps zooplankton in the depths

   Climate change is affecting the vertical migration of zooplankton in the Arctic, with potential implications for the entire Arctic ecosystem, finds a new study, published today in Nature Climate Change.

2. Flying campaign to future-proof sea ice measurements

   An ambitious flying campaign out of British Antarctic Survey’s Rothera Research Station over the Weddell Sea this month (December) aims to calibrate the data collected from two important satellites that […]
