Angelo Gavezzotti, an X-ray crystallographer by training who then devoted himself to theoretical chemistry after his graduation in chemistry, has been researcher, then associate and full professor of physical chemistry at the University of Milano, 1971–2010. He was co-editor of Acta Crystallographica (1988–1991), director of the Department of Structural Chemistry, University of Milano (1997–1999), a member of the editorial board of CrystEngComm, Royal Society of Chemistry (2005–2008), and a member of the Coordination Committee of the European Science Foundation Network on crystal polymorphism (2001–2002). He is a Fellow of the Royal Society of Chemistry, UK. He has been awarded the Trueblood prize "For exceptional achievement in computational or chemical crystallography," by the American Crystallographic Association (2007) and the Mario Mammi Memorial Gold Medal by the Italian Crystallographic Association (2015). He is the author of more than 170 full papers in major refereed journals or chapters in books from major publishers, of three books, and of countless contributions to other journals and conference proceedings. He has given more than 130 invited seminars, lectures, and keynote lectures at universities or major congresses and other international events and at chemical companies worldwide.

"This book provides a bridge between crystallography and computational chemistry with considerable insight and humour… This book is a complement to rigorous text books on crystallography, quantum mechanics, thermodynamics and molecular simulation, aimed at helping those studying the condensed phases of organic molecules to appreciate the interdisciplinary nature of the field. I recommended purchase for my institutional library, for its value to PhD and early career researchers as an aid to understanding the literature. Late-career scientists who have been through the development of ideas in the organic solid-state community may enjoy seeing how Gavezzotti’s provoking views have developed." --Sarah L.
