Nicolas has been studying environmental sciences for 5 years. As part of his second year of Master’s degree at the University of Burgundy (MASTER II Soil, Water, Environment), he has the opportunity to carry out a six-month internship in collaboration with SNO M-TROPICS / MSEC in the north of Laos. His internship is part of the NARIBACT EC2CO project, which aims to understand and model the role of underground flows in the dissemination of E. coli in humid tropical zones. His main missions will consist in carrying out a set of hydrogeochemical analyzes in order to better understand the spatial and the temporal variabilities of the groundwater contributions to the river among a network of rivers in Northern Lao PDR (Mekong and tributaries). Welcome Nicolas!
