The Master 2 in Molecular Chemistry and Interfaces (M2 MOCHI), a joint program between ENS Paris-Saclay and the Institut Polytechnique de Paris (IPP), is a program focused on molecular chemistry with an interdisciplinary approach to related fields and societal challenges (biology, health, energy, the environment, and materials science). The program requires a solid foundation in organic and organometallic chemistry. The four-month theoretical component, conducted entirely in English, is complemented by a six-month research project.
