Dear Colleagues,

We warmly invite you to join us in celebrating 25 years of DSS at the 25th International Symposium on Disordered Systems: Theory and Its Applications (DSS-2025), organized by the Nonlinear Science Working Group, to be held from 27 to 29 November 2025 in Istanbul, Türkiye.

Since 2001, the Nonlinear Science Working Group has been serving the complexity science community by organizing the Disordered Systems Symposia (DSS), one of the oldest and longest-running international events dedicated to disordered systems, complexity, and nonlinearity. DSS provides a vital platform that brings together leading specialists, early-career researchers, and participants from diverse fields to exchange ideas, foster collaboration, and advance research in complexity science.

With DSS-2025, we continue two initiatives introduced to further serve and expand the community. The Murray Gell-Mann Memorial Lectures honor his pioneering contributions to complexity science and his visionary spirit. The WOMPLEXITY initiative promotes the visibility of women in complexity science. These efforts demonstrate our ongoing commitment to supporting diversity, inclusion, and excellence within the complexity science community.

See you in Istanbul,
G.Cigdem Yalcin
Istanbul Unniversity, Physics Department
