Alessandro Sisto

Alessandro Sisto is an Associate Professor at Heriot-Watt University, specializing in Geometric Group Theory with a focus on generalizations of hyperbolic groups. He leads research in the GGT (Geometric Group Theory) group at Heriot-Watt and advises PhD students including current student Giorgio Mangioni and former students Stefanie Zbinden, Antoine Goldsborough, and Davide Spriano. His work intersects geometric topology, low-dimensional topology, and hyperbolic geometry. Sisto maintains an active blog and collaborates internationally on projects such as the Centre for Doctoral Training in Algebra, Geometry, and Quantum Fields.

Education: Completed his PhD at the University of Oxford under the supervision of Cornelia Druțu.

Research interests span hierarchical hyperbolicity, coarse median structures, and the interplay between group theory and geometric spaces. His recent articles explore topics like bounded cohomology, asymptotically CAT(0) metrics, and cohomological characterizations of hyperbolicity. Sisto's contributions often blend algebraic, geometric, and probabilistic methods to advance foundational questions in geometric group theory.

Labs/Teams: Active member of the GGT group at Heriot-Watt. Collaborations include projects on mapping class groups, Artin groups, and hyperbolic 3-manifolds.
