Bjorn Poonen

Bjorn Poonen is a mathematician known for his work in number theory, especially in the areas of arithmetic geometry, algebraic geometry, and the arithmetic of elliptic curves. He has contributed to various advances in the understanding of rational points on algebraic varieties and has worked on topics related to the Birch and Swinnerton-Dyer conjecture, an important conjecture in number theory that connects the number of rational points on an elliptic curve to the behavior of an associated L-function.
