**Some works of Maryam Mirzakhani (1977-2017)**: I will present in this lecture some of the works of Maryam Mirzakhani. Maryam Mirzakhani was a mathematician working in hyperbolic geometry, studying curves on surfaces and more precisely their distribution. Rather than giving a precise account of her numerous and amazing results, I will use one of her work as a thread ? or a pretext ? to present some basic ideas of geometry as well as a little history of the subject: What is a surface? What is hyperbolic geometry? How do mathematicians count curves on surfaces?
