Élisabeth Guazzelli (born 17 January 1955)[1] is a French experimental physicist whose research concerns fluid mechanics, suspensions of particles in liquids, and particle-laden flows.
[3] Guazzelli was a student from 1974 to 1979 at the École normale supérieure de Fontenay-aux-Roses [fr], while earning bachelor's and master's degrees in physics through Paris-Sud University in 1974 and 1979 respectively.
She was deputy director of the Institut Universitaire des Systèmes Thermiques Industriels (IUSTI) at Aix-Marseille University from 2008 to 2011, and since 2012 has been rector of the International Centre for Mechanical Sciences (CISM), a non-profit scientific organization based in Udine, Italy.
[2] Guazzelli is the coauthor with Jeffrey F. Morris of the book A Physical Introduction to Suspension Dynamics (Cambridge University Press, 2012).
[6] In 2021, Guazzelli was elected a Member of the National Academy of Engineering, "for experiments and theory that enhance understanding of dispersed particulate systems".
