Dan Andersson (Master)

Dan aims to better understand the spatial variability of heavy metal pollution in the sediments of Lake Geneva, based on data from the CIPEL as well as on sampling

Imene Benali (invited Post-doc)

Imene and our group collaborate for more than 5 years. Imene is assessing the impact of pollutant in Algeria by measuring biomarkers in different types of mussels.

Imene is working at the University USTO/MB at Oran, Algeria.

Laurent Boualit (PhD) – personal website

Laurent is  assessing the effects of chemicals on amphibian physiology, morphology, behavior (i.e. personality, dispersal), and life history traits (i.e. survival and growth) at embryonic and larval stages. He will also examine the delayed effects of chemical exposure at aquatic stages on physiology, morphology, behavior, and life history traits after metamorphosis.

Joël Davila Estevez (Master)

Joël aims in determining the antibiotic concentrations in wastewater at different locations in Lausanne  city and in evaluating the impacts on bacteria.

Vincenzo Guzzardi (Master)

Vincenzo aims in assessing the risk of the pharmaceuticals issued from senior citizen buildings by determining their relations with the differents water treatment plant and concentrations of drugs in rivers in collaboration with Unisanté at the CHUV

Vidhi Kamdar (Master)

Vidhi aims in determining the concentrations of disinfectants in swiss waters following the covid-19 pandemic and the risks they might pose.

Jason King (Master)

The Dynamic project, carried out jointly by Unisanté at the CHUV, the EPFL and the Unil, aims in improving the medical care of children in rural dispensaries in Tanzania through the use of an electronic tablet and software for diagnostics. Jason’s work consists of carrying out a life-cycle analysis of the project as a whole, and at evaluating the fate of these tablets at the end of their life.

Raphaël Müller (Master)

Raphaël aims in analysing the heavy metals concentrations in Quagga mussels (Dreissena rostriformis) at different locations in the Geneva Lake. Indeed, bivalves are filtrating water and thus bioaccumulate heavy metals. Their analysis should therefore give a good idea of the pollution at a given place.

Renaud Nasch (Master)

Renaud aims in modelling the evolution of the plume of dissolved micropollutants at the outlet of a wastewater treatment plant in a large lake by combining water column measurements coupled with a recently developed hydrological model of Lake Geneva (in collaboration with Damien Bouffard, Eawag)

Christophe Reis (Master)

Christophe’s objective is to determine if the Quagga mussel can be used as a bioindicator of heavy metal pollution using metallothionein (MTs), a metal regulatory protein produced by the Quagga mussel when it absorbs heavy metals. To achieve this goal, he will try to find a correlation between the level of MTs in the mussel and the amount of heavy metals found in the sediments where it lived.

Sophie Schnurr (Master)

Sophie aims at measuring the percentage of chlorine incorporation into organic compounds as a result of the reaction between chemical oxidants and water matrix components (in collaboration with Eawag-EPFL).

Floriane Tisserand (PhD)

Floriane is assessing the effects of chemicals on microcrustacea like daphnids. She is investigating the life history traits (i.e. survival and growth) as well as the effects at the biochemical level.

Assiata Traore Dosso (PhD)

Assiata is assessing the fate and behaviour, as weel as the environmental and health impact of chemicals used for gold extraction. She focuses her study on the mines situated in the region of Hiré (Southern Ivory Cost). See « mine d’or ou mine de malheur«
