She is currently at the Center for Snow Studies (CEN CNRM Météo-France, Grenoble) to explore this porous or evolutionary granular material that is snow.

Early Career Researcher Awards

Following the same spirit as ICAA16 in Montreal, six awards will be distributed to early career researchers on the basis of the quality of their scientific research and on their ability to communicate these results.

Three of these awards have been attributed to PhD students (or having defended their thesis after Nov. 1st, 2018), and three have been attributed to post-doctoral researchers having defended their thesis after Nov. 1st, 2015.

The awardees will give a 15 minutes plenary talk during the conference.
