Keti Tenenblat

Keti Tenenblat (born 27 November 1944 in Izmir, Turkey) is a Turkish-Brazilian mathematician working on Riemannian geometry, the applications of differential geometry to partial differential equations, and Finsler geometry.
She earned her Ph.D. from IMPA in 1972 under the supervision of Manfredo do Carmo.
She is a recipient of Brazil's National Order of Scientific Merit in Mathematics, Emeritus Professor at the University of Brasília, and was President of the Brazilian Mathematical Society in 1989–1991. She has been a member of the Brazilian Academy of Sciences since 1991.
She is the author of the books Introdução à geometria diferencial (1988), and Transformações de superfícies e aplicações (1981).
