Former colleagues

Emilie Sammali

Emilie Sammali joined eOde in June 2019 and leaved in December 2021. She is a hydrogeologist graduated from the CHYN and also holds a Bachelor’s degree in Natural Systems. She is particularly interested in polluted sites. The study of a chlorinated plume in a Danish aquifer remediated with liquid activated carbon was the subject of her thesis. Through small jobs in Alpgeo office in Sierre or Swisstopo, Emilie was able to complete her training and acquire solid knowledge in hydrogeology.
