Salvatore Torquato (born February 10, 1954 in Falerna ) is an Italian engineer .

Life

Torquato studied at Syracuse University with a bachelor's degree in 1975 and the State University of New York at Stony Brook with a master's degree in 1977 and a doctorate in mechanics in 1980. He was from 1982 Assistant Professor at North Carolina State University , at the he became professor for mechanics and aircraft construction in 1991. He later became a professor at Princeton University , where he conducts interdisciplinary research in various faculties. He is Lewis Bernard Professor in the Faculty of Chemistry, but also at the Princeton Center for Theoretical Science and at the Princeton Institute for the Science and Technology of Materials. He has been to the Institute for Advanced Study in Princeton several times .

In 1990/91 he was visiting professor at the Courant Institute .

He deals with applied mathematics, materials science, soft matter, biophysics, and engineering.

He investigated the random distribution of spheres (and introduced the term maximally random jammed state for packings), formulated a conjecture similar to the Kepler conjecture for closest packing non-spherical particles and found evidence that the closest packing of spheres are not regular in higher dimensions as in low dimensions.

He created an algorithm for determining the microstructure in random media. He developed optimization methods for the design of novel materials on the drawing board , for example using inverse methods of statistical mechanics.

He wrote a monograph on heterogeneous randomly arranged materials and introduced new phases (disordered hyperuniformity, disordered hyperuniformity) between crystal and liquid. In 2018 he found an example of this in the arrangement of prime numbers in certain large intervals and at the same time a new class of many-body systems with a point-like diffraction spectrum, which he called effectively limit-periodic.

Torquato simulated cancer growth using cellular automata in 2000.

He is a Fellow of the American Physical Society , SIAM, and the American Society of Mechanical Engineers (ASME). He is Simons Fellow, was a Guggenheim Fellow, received the William Prager Medal in 2004 , received the Ralph Kleinman Prize from SIAM and in 2017 the Joel Henry Hildebrand Award from the American Chemical Society . He is one of the most highly cited scientists.
