Roberto Carlos Salvarezza was born on 30 January 1952 in Lanús Oeste, in the southern side of the Greater Buenos Aires conurbation in Buenos Aires Province.[1][2] He attended high school at the prestigious Colegio Nacional de Buenos Aires, and later finished his biochemistry licenciatura at the University of Buenos Aires (UBA) in 1977.[1] In 1981 he finished his PhD in the same university; his dissertation was titled "The microbiological corrosion of aluminium and alloys in water-combustion systems" (Spanish: "Corrosión microbiológica del aluminio y aleaciones en sistemas agua-combustible").[3]
In 1992 he founded the Nanoscopy Laboratory of the Theoretical and Applied Physicochemical Research (Spanish: Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicadas; INIFTA) at the National University of La Plata. He worked as director of said laboratory and also of the INIFTA.[4] Throughout his career, Salvarezza has authored over 300 publications.[2]
In July 2016, Salvarezza was elected representative of the Exact and Natural Sciences area in the CONICET directory, but his designation was not approved by the government in an unprecedented move. This caused controversy among the scientific community, wherein it was decried as "political discrimination". Salvarezza received the backing of the Directive Council of the UBA Faculty of Exact and Natural Sciences,[6] the World Federation of Scientific Workers[7] and the CyTa group.[8]
In December 2019, Salvarezza was appointed Minister of Science, Technology and Innovation by newly elected president Alberto Fernández, succeeding Barañao.[1] The Ministry had been downgraded to a secretariat during the presidency of Mauricio Macri, but it was restored to its ministerial status with Salvarezza's appointment.[11] He was replaced with Daniel Filmus on 20 September 2021 as part of a cabinet reshuffle, following the government's poor showings in the 2021 legislative primary elections.[12]
