He is also a Fellow of the American Academy of Arts and Sciences, a Member of the Spanish Royal Academy of Sciences, and a Member of the Brazilian Academy of Sciences. Graduating from Novosibirsk State University in Russia, Efim Zelmanov served as a Professor at the University of Chicago, Yale University, and other top universities worldwide. He was awarded the Fields Medal, the highest honor in mathematics, in 1994, elected a member of the National Academy of Sciences in 2001, and elected a foreign member of the Chinese Academy of Science in 2021. Being a Chair Professor at the Southern University of Science and Technology and the Director of the Shenzhen International Center for Mathematics, Efim Zelmanov's main research interests are non-associative algebras, group theory, etc. Efim Zelmanov developed the structural theory of Jordan algebra, successfully extending the theory of finite dimensional reduction of contemporary numbers to infinite dimensions, and tackling the profound problems raised by Jordan, John von Neumann, and Weiner in 1938, as well as the Bernstein conjecture with a complete solution.
