Input of suspended solids in the Vidy Bay and consequences for the sediment quality.
In this master project, we aim in modelling the suspended solids transport from the inputs (river, stormwater overflow, waste water treatment plant) to the Bay. In particular, we would like to evaluate if we can predict the repartition of the metals in the Bay.
In collaboration with Damien Bouffard, eawag.

Development of a non invasive method for measuring biochemical biomarker on amphibians.
In this master project, we aim at developing non-invasive methods for measuring molecular biomarkers in amphibians’ saliva and/or epidermal mucus. Developing such methods would be of greatest importance for environmental biomonitoring and is highly consistent with the « Refinement » part of the principles of the 3R’s (Russel et al., 1959).
Co-supervised by Laurent Boualit, PhD, FGSE.
**********
Hydrology and pollution of ponds fed by groundwater.
In this master project, we aim in investigating the hydrology of ponds called “Les Bons” that are situated close to Lavigny (VD) and Mollens (VD), and that have a specific hydrology as they are fed by grounwater. The goal is to survey both the water level and the pollution, mainly pesticides, to evaluate the risk for the ecosystem.
Co-supervised by Dr Marc-Henri Derron, Lecturer, FGSE.

Soil ecotoxicology of agricultural fields of Unil.
In this master project, we aim in evaluating the soil ecotoxicity of two parcels of the domain of Unil. Soil analyses (granulometry, organic matter, pesticides, heavy metals) will be performed. The pesticides and heavy metals analyses will allow soil risk assessment. In parallel, ecotoxicity tests will be done for comparison.
in collaboration with Dr Stéphanie Grand, Lecturer, FGSE.

- Development of non-invasive method for measuring biochemical biomarkers on amphibians
In this master project, we aim at developing non-invasive methods for measuring molecular biomarkers in amphibians’ saliva and/or epidermal mucus. Developing such methods would be of greatest importance for environmental biomonitoring and is highly consistent with the « Refinement » part of the principles of the 3R’s (Russel et al., 1959). - Pesticides and antibiotics in ponds. Risk assessment for amphibians.
In this master project, we aim in characterizing the exposure of amphibians to pesticides and antibiotics in ponds. In a first step, the student will have to determine potentially polluted and unpolluted sites based on GIS. Second, he/she will have to collect samples from these sites that will be analysed at the cantonal laboratory in Epalinges (in collaboration with the student). Finally, the student will have to estimate the risk for amphibians due to the exposure measured.
