## Summary
Grigori Perelman is a Russian mathematician born in 1966, known for his groundbreaking contributions to differential geometry and topology, particularly his proof of the Poincaré conjecture. His work revolutionized the field and remains a landmark achievement in mathematical research.

## Biography
- Born: 1966
- Nationality: Russian
- Education: Attended Saint Petersburg Lyceum 239 and the St. Petersburg Department of Steklov Institute of Mathematics of the Russian Academy of Sciences
- Known for: Proving the Poincaré conjecture, a major unsolved problem in geometric topology
- Employer(s): St. Petersburg Department of Steklov Institute of Mathematics, Russian Academy of Sciences
- Field(s): Differential geometry, topology, Riemannian geometry

## Contributions
- **Poincaré Conjecture Proof (2002–2003)**: Perelman's solution to the Poincaré conjecture, which states that every simply connected, closed 3-manifold is homeomorphic to the 3-sphere, was a major breakthrough in geometric topology. His work introduced novel techniques in Riemannian geometry, including the use of Ricci flow and the concept of entropy, which became foundational in the field.
- **Geometrization Conjecture**: Perelman's research also contributed to the geometrization conjecture, which posits that closed 3-manifolds can be uniquely decomposed into pieces with one of eight possible geometric structures. His methods in this area further advanced the understanding of 3-dimensional manifolds.
- **Soul Theorem**: Perelman's work on the soul theorem, a result in differential geometry, provided insights into the structure of complete Riemannian manifolds with non-negative Ricci curvature.
