Tommaso Ruggeri - Biography#

Professor Ruggeri became a full professor of Rational Mechanics at the University of Bologna in 1980. He is the author of 280 publications, almost all of them in international journals, including 4 books. His research activity is dedicated to various problems of mechanics, and in particular, he has given fundamental results on the propagation of non-linear waves and in classical and relativistic continuous media. In the first field, he has produced original and widely cited contributions concerning the symmetrization of hyperbolic systems of balance laws when they are compatible with a convex entropy density and non-linear problems concerning acceleration and shock waves. In the field of non-equilibrium thermodynamics, he was one of the founders of modern Extended Thermodynamics and wrote, together with Ingo Mueller, the well-known book Rational Extended Thermodynamics (Springer-Verlag, 1993 and 1998) which has over 2200 citations and is considered a seminal book in studies on the thermodynamics of non-equilibrium. This theory allows a connection between the macroscopic scale (continuous approach) and the mesoscopic scale (kinetic theory). Recent articles are devoted to the inclusion of polyatomic gases, moderately dense gases, and gas mixtures in the theory. These latest results are collected in recent books written in collaboration with Masaru Sugiyama: Rational Extended Thermodynamics beyond Monatomic Gas, (Springer, 2015) and Classical and Relativistic Rational Extended Thermodynamics of Gases (Springer, 2021). According to Google Scholar Citations, Prof. Ruggeri has 8512 citations with h-index = 42 and i-index = 126 and belongs to the list of Top Italian Scientists. He was elected at 52 years of age as member of the Accademia Nazionale dei Lincei (Italian National Academy), the oldest Academy of Sciences in the West Countries, as well as other Academies (Napoli and Bologna).

He has been invited as a plenary speaker in various international meetings and has been a visiting professor in many Universities (Stanford, Brown, Paris, Berlin, Seoul, Taipei, Mumbai, Hong Kong, Sydney, Kyoto, Beijing, etc.).

He is an associate editor in several journals and has had many students who are now professors. He was also Director of the National Group of Mathematical Physics and President of the Scientific Committee of the Istituto Nazionale di Alta Matematica.
