    Lionel Vacher's scientific research seeks to decipher the isotopic composition of the water reservoir in the early Solar System from the study of secondary alteration minerals in primitive meteorites and to estimate the timing of early aqueous activity of asteroids from isotopic dating on extraterrestrial carbonates.
