|Julia Gonzalez Holguera |
Institut of Earth Surface Dynamics
Julia obtained an MSci in chemistry from Imperial College (UK). She came to Lausanne as an exchange student to complete her master’s pro- ject at the EPFL, looking at photochemical processes in dye sensitized solar cells. Julia took advantage of the close proximity of the UNIL to follow courses in Environmental Sciences.
|Francesco Femi Marafatto |
Francesco Femi was born in Nigeria, spent his childhood in Kenya and Belgium, and then moved to Italy at age 14. He decided to study Geology at the university because fascinated by science and the idea of travelling around the world for a living. During his bachelor’s courses he became interested in environmental geology, especially because the time he spent in Africa made him sensitive to environmental issues. For his Master’s thesis, he used stable isotope methods to study chromium oxidation and reduction reactions in a contaminated aquifer in northern Italy. For his PhD, Francesco is investigating the molecular scale mecha- nism of manganese oxide photoreduction as a function of their physicochemical properties, and the implication of this process to the fate of contaminants in the environment.
|Sassi Benkaddour |
Sassi is from Toulon in the south of France where he was studying chemistry during his Bachelor’s degree. After these three years, he chose to study analytical and environmental chemistry for his Master’s degree, during which he had the opportunity to participate in a first project related with the detection of antimony in neutral pH conditions using gold microwire electrode at the University of Liverpool with Dr. Pascal Salaun. He worked on a second project looking at the redox properties and reactivity of manganese oxide minerals here at the University of Lausanne with Dr. Jasquelin Peña. Sassi is now working on the rates and mechanisms of water and organic carbon oxidation coupled to MnO2 photoreduction for his PhD.
