Description of the research group

The LCOS offers the possibility of internships (IUT, M1-M2 masters, chemistry schools ...) or to prepare a thesis at the University of Strasbourg. LCOS is recognized for providing excellent training in synthetic organic chemistry.

LCOS offers research training based on preparative organic chemistry. This makes it possible to address a wide variety of research fields and includes the use of conventional analytical techniques (NMR, IR, UV, HPLC, MS, etc.). This implies that the work will never be monolithic but will necessarily include the use of the whole range of the synthetist, both at the documentary and preparatory or analytical level. The thesis is always considered under its double aspect of original scientific work and period of apprenticeship of a profession.
