the 2020 Schauder Medal goes to the distinguished Italian mathematician

**Professor Susanna Terracini from the University of Torino, Italy**

in recognition of her significant achievements in development of variational methods and contributions to dynamics of differential equations, in particular for n-body problems, nonlinear reaction diffusion equations as well as Schrödinger systems.

Prof. Terracini’s research interests include different directions in the field of nonlinear analysis with application to the variational methods, to chaotic and complex trajectories in Hamiltonian dynamical systems, especially in celestial mechanics, including the n-body problem, and pattern formation mechanisms for nonlinear reaction diffusion and Schrödinger systems. Prof. Terracini is the author of about 118 papers, published in major international mathematical journals, 5 books and is on the editorial board of a number of national and international journals.

Professor Susanna Terracini earned her MS degree in 1986 in mathematics at the University of Torino and completed her Ph.D. at the SISSA (Scuola Internazionale Superiore di Studi Avanzati); her Ph.D. dissertation, Periodic Solutions to Singular Newtonian Systems, was supervised by Ivar Ekeland and Sergio Solimini. In 1988-89 she received a research fellowship C.N.R. at CEREMADE (University of Paris IX). In 1990-2001 she was a researcher and associated professor at the Department of Mathematics, Politecnico of Milano. In 2001-12 she had a full professor position at the Department of Mathematics, University of Milano Bicocca. From 2012 she has been a full professor at the Department of Mathematics „Giuseppe Peano”, University of Torino. Professor Susanna Terracini was awarded the C. Vinti prize in 2003 and the B. Finzi prize in 2007. She was also the convenor of the association European Women in Mathematics (EWM) from 2013 to 2015. It is worth adding that she was the principal investigator of the Research Project of National Interest (PRIN2009) project Critical Point Theory and Perturbative Methods for Nonlinear Differential Equations, and the principal investigator of the ERC Advanced Grant, Complex Patterns for Strongly Interacting Dynamical Systems. Her joint paper with D.L. Ferrario “On the Existence of Collisionless Equivariant Minimizers for the Classical n-body Problem” published in Inventiones Mathematicae was selected as “featured review” on Mathematical Reviews.
