Lorenzo Ruffoni

Lorenzo Ruffoni is an Assistant Professor at Binghamton University, State University of New York, in the Department of Mathematics and Statistics. He previously held postdoctoral positions at Tufts University (with Genevieve Walsh) and Florida State University (with Phil Bowers). He earned his PhD in Mathematics from the University of Bologna under Stefano Francaviglia. His research focuses on geometric group theory, hyperbolic groups, cube complexes, and complex/hyperbolic/projective structures on manifolds. He has contributed to topics such as cubulation of hyperbolic groups, circle packings on surfaces with conical singularities, and deformations of projective structures. His work often intersects with low-dimensional topology and differential geometry.

His research interests include:

• Geometric group theory (e.g., Gromov hyperbolic groups, right-angled Artin groups).
• Complex and hyperbolic structures on surfaces and higher-dimensional manifolds.
• Projective structures, conformal geometry, and Teichmüller theory.

Ruffoni has published widely in journals like Inventiones Mathematicae, Proceedings of the American Mathematical Society, and Algebraic and Geometric Topology. His articles explore themes such as cubulation techniques, geometric invariants of manifolds, and deformations of geometric structures. He has also organized conferences and given talks at institutions like Tulane University and the CRM Montreal. His research is supported by grants from the Simons Foundation.
