Professor Michele Parrinello has studied a large number of different systems, but there is one to which his name is especially linked: water. The pioneering Ab initio liquid water simulation[16] was published by Parrinello and co-workers and that landmark study was the beginning of a new era for the research on water, solvation, liquid state chemistry, and hydrogen-bonded systems in general in which computer simulations are taking a leading role not only for the deepening of the microscopic understanding but also in the prediction of unforeseen properties and phenomena. His outstanding achievements in the physical sciences were honored when he was elected member/fellow of the American Physical Society (1991), the International Academy of Quantum Molecular Sciences (1995), the Berlin-Brandenburgische Akademie der Wissenschaften (2000), the Royal Society (2004), the European Academy of Sciences (2004), and the World Association of Theoretically Oriented Chemists (2005) among others. He is a current professor for Computational Science at the ETH Zurich.
