In September 1930, while studying Electrical Engineering, he was appointed extraordinary teacher of the faculty of Sciences of the University of Porto.
In June 1945, after completing his doctorate degree in Mathematical Sciences with the theses "Estudo de Alguns Funcionais e sua aplicação à Resolução de Equações de Derivadas Parciais", he received the title of Doctor. He was one of the 7 new doctors of the University of Porto who received the doctoral insignia in a public ceremony held on 16 June 1945, along with Joaquim Rodrigues Santos Júnior, Arnaldo Deodato Fonseca Roseira, Leopoldina Ferreira Paulo, Judite dos Santos Pereira, Joaquim Augusto Ribeiro Sarmento and José Ramos Bandeira.

In December 1957, he competed for the position of extraordinary professor of the 1st group – Analysis and Geometry -, of the 1st Department (Mathematical Sciences), and was approved unanimously. At that time, he submitted a theses entitled "Estudo de algumas questões de Geometria e sua aplicação à Geometria de Lobatchevsky". He was appointed by Order of 27 December 1957, published in the Government Gazette (2nd Series, no. 17, of 21 January 1958), and was sworn in on the 22nd of the same month and year.
