Andrew Casson is a mathematician known for his work in the field of topology, particularly in the study of 3-manifolds and geometric topology. He has made significant contributions to the understanding of the structure of 3-manifolds through various techniques, including the development of Casson invariant, which is an important concept in the study of knots and links in 3-dimensional spaces.
