Ludmila Bourchtein

Bourchtein received a bachelor's degree in mathematics from the Far Eastern Federal University in Vladivostok in 1960,^[3] and continued to work at Far Eastern Federal University for 34 years as an assistant, associate, and full professor.^[1] Meanwhile, she earned a doctorate through Saint Petersburg State University in 1968,^[3] with a dissertation on the solution of functional equations for complex analytic functions on the unit circle.^[2]

She joined the Federal University of Pelotas in Brazil in 1997,^[4] as an associate professor and later as a full professor,^[1] retired in 2010^[4] and was named a professor emerita in 2019.^[1] At the Federal University of Pelotas, one of her students was Adriana Neumann de Oliveira, who credits Bourchtein as being her first female role model in mathematics.^[5]
