Elena Moldovan Popoviciu (26 August 1924–24 June 2009) was a Romanian mathematician known for her work in functional analysis and specializing in generalizations of the concept of a convex function.
She studied mathematics at the Victor Babeș University in Cluj, earning a bachelor's degree there in 1947; afterwards, she became a schoolteacher.
She returned to the university for doctoral study in the early 1950s, initially working with Grigore Calugăreanu, but she soon came under the influence of Tiberiu Popoviciu and began working with him in functional analysis.
[2] She married Popoviciu in 1964, remained at the university, and became a full professor there in 1969.
[3] Popoviciu won the Simion Stoilow Prize of the Romanian Academy, for her achievements in mathematics, in 1972.
