Rafael Mariano Grossi (born 1961)
Early life and studies
In 1983, Grossi graduated from the Pontifical Catholic University of Argentina with a BA in Political Science, and in 1985 he joined the Argentine foreign service. In 1997, he graduated from the University of Geneva and the Graduate Institute of International Studies with an MA and PhD in History, International Relations, and International Politics.
Career
Grossi began working in nuclear policy during a collaboration between the Argentine foreign service and
INVAP.
Between 1997 and 2000, he was the President of the United Nations Group of Government Experts on the International Weapons Registry, and later became adviser to the Assistant Secretary-General of the United Nations on disarmament.
From 2002 to 2007, he was Chief of Staff to Director General Mohamed ElBaradei the International Atomic Energy Agency and the Organisation for the Prohibition of Chemical Weapons.
During his work for the Argentine foreign service, Grossi was the General Director of Political Coordination of the Ministry of Foreign Affairs and Worship, Ambassador to Belgium and the Argentine Representative to the United Nations Office at Geneva.
In September 2015, the Argentine government announced the nomination of Grossi as a candidate for Director General of the IAEA, with support from other countries in Latin America and the Caribbean. In 2016, however, the government of Mauricio Macri withdrew its support to promote Susana Malcorra's candidacy as UN Secretary General.
In 2017, President Macri announced that he would nominate Grossi for the presidency of the Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons to be held in 2020.
Contribution to the search of ARA San Juan
In November 2017, after the disappearance of ARA
San Juan, Grossi had the idea of reviewing the records of the hydro-acoustic stations of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) as an alternative to obtain clues about what happened with the submarine. He contacted
Lassina Zerbo, the Executive Secretary of the CTBTO, and convinced him of doing such reviews. His efforts paid off: the agency subsequently reported on "an underwater impulse event" occurred near the last known position of the submarine by the listening posts on
Ascension Island and
Crozet Islands at .
The remains of the ill-fated ship were found a year later, about twenty kilometers from the estimated position based on the cited records.
Director General of IAEA
On August 2, 2019, Grossi was presented as the Argentine candidate to become the Director General of IAEA.
On 28 October, 2019, the IAEA Board of Governors held its first vote to elect the new Director General, but none of the candidates secured the two-thirds majority in the 35-member IAEA Board of Governors needed to be elected. The next day, 29 October, the second voting round was held, and Grossi won 24 votes, which is one more than the 23 required for Director General Appointment, and became the first Latin American to head the organisation.
He assumed office on 3 December 2019.
In August 2022, Grossi led a team of IAEA inspectors to the Zaporizhzhia Nuclear Power Plant in Russian-occupied southern Ukraine.
Since 2022, Grossi had been in the spotlight to obtain information on nuclear materials from Iran to re-negotiate the
JCPOA. In September 2022, he continued to express concerns about traces of uranium found at three Iranian nuclear sites. Grossi told a press conference in Vienna that he is "under political pressure". Iran has long denied that it seeks nuclear weapons for defense purposes.
Following the outcome of the Iran-Israel War, Iran's leadership spoke against him, some were even quoted saying he should be “arrested and executed”,
Candidacy for United Nations Secretary-General
In 2025, Grossi publicly confirmed his interest in being a candidate in the 2026 United Nations Secretary-General selection.
