This week both iEES Paris and GET laboratories welcomed Prof. Kyunghwa CHO and 3 of his PhD students within the PHC STAR collaboration funded by Campus France, involving iEES Paris, GET, and UNIST. On April 3, we had a seminar in Toulouse to present on-going work from both sides, including hyper-spectral imagery and its application on water quality monitoring, E. coli monitoring and modelling at catchment scale, mercury fate in surface water, soil erosion, and B. pseudomallei fate in soils. Several of these studies are using long-term data collected by M-TROPICS in Lao PDR.
