 In 1924, Beloch completed her "libera docenza" (a degree that at that time had to be obtained before one could become a professor) and three years later she became a full professor at the University of Ferrara
where she taught until her retirement (1955).Her main scientific interests were in algebraic geometry, algebraic topology and photogrammetry.After her thesis, she worked on classification of algebraic surfaces studying the configurations of lines that could lie on surfaces.
