Short Resume

Serge Stoll received his PhD in Physical Chemistry by working on colloid coagulation processes in the group of Professor Pefferkorn at the University Louis Pasteur, France. After joining Professor Buffle's research group in the departement of analytical, inorganic and applied chemistry at the University of Geneva, he became a senior scientist. Then he was promoted senior lecturer, teaching environmental, soft-condensed and analytical chemistry to undergraduate and graduate students. He has co-authored more than 75 publications in referred international journals, supervised about 10 PhD thesis works, and was chosen for his work to represent Switzerland in 1998 at the CERC3 Workshop on Colloidal Synthesis and Characterisation, Bristol UK.

Teaching Activities

Main emphasis lies on courses in colloid and polymer chemistry, which include introductory to advanced courses for students, and courses for professionals. He further participate in teaching of general chemistry within the chemistry curriculum, and advanced courses in Environmental Sciences (Aquatic chemistry, Chemical processes in the environment, water quality and management, Atmosphere Chemistry) at the Geneva Institute of Environmental Sciences (ISE). He also teach general chemistry at the medicine faculty.

Research Interests

The fate and transport of contaminants, such as trace metal elements, pesticides and manufactured nanoparticles, introduced by rivers or by atmospheric inputs in waters by human activities, needs to be understood to evaluate their long-term impacts on the ecosystems as well as their influences and effects on biota. Numerical modelling as well as experimental studies using state-of-the-art techniques are performed in his group to understand the factors controlling the structure, diffusion, aggregation and sedimentation of colloids, biopolymers and manufactured nanoparticles. In particular dynamic modelling (Monte Carlo and molecular dynamics) is used to understand the association of large biopolymers and polyelectrolytes with colloids and nanoparticles as well as the evolution of their aggregates and sedimentation rates. In all cases a major goal is to relate molecular and supramolecular processes to macroscopic ones.

This fundamental research is being applied within environmental chemistry and for industrial process control such as the rational design of flocculants used in water treatment and drinking water production, as well as to better understand the fate and impact of manufactured nanoparticles in aquatic systems.
