Humboldt Fellowships are among the prestigious international awards for research and travel. They are designed to recognize internationally-leading senior researchers from all scholarly disciplines for their record of achievements, and to facilitate visits to university and research centers in Germany. Leonardo, who holds the Renaissance Chair of Theoretical Physics, was nominated by the Ludwig-Maximilians University in Munich, and has been awarded a Carl Friedrich von Siemens Research Award of the Alexander von Humboldt Foundation, in recognition of his accomplishments in research and teaching. The fellowship will make possible flexible visits to Munich to lecture and develop collaborations.
