This special issue is dedicated to Giovanni Landi on the occasion of his 60th birthday. The papers in this volume span a wide range of topics in Noncommutative Geometry, reflecting Landi's research activities and achievements of the last thirty years.

We are grateful to all the authors who contributed to this project and to the referees for providing constructive reviews. Many of the papers were also reported at the corresponding conference held at Grand Hotel de Rose in Scalea (Italy), on September 16–20, 2019. We would like to thank all the speakers and the participants for contributing to the success of the conference.
