David Avnir is a Chemistry Professor (Emeritus) at the Hebrew University of Jerusalem, where he received all his academic education. His current scientific activities include organically doped metals, theoretical and experimental aspects of chirality and symmetry, sol-gel hybrid materials and biomaterials, and astrochemistry. Earlier major interests included fractals theory in chemistry and physics, and far-from-equilibrium phenomena such as chemically driven hydrodynamic instabilities. He has co-authored 415 papers, which are highly cited (GoogleScholar: h=83, ~38,000 citations). He was the first Chairman of the Board of the International Sol-Gel Society (ISGS). Some of his recognitions include the Israel Chemical Society Prize (2011), the Life Achievement Award of the ISGS (2013), and being elected as a Distinguished Scientist by the Chinese Academy of Sciences (2018).
