Irans president on Sunday appointed a new director of the countrys nuclear department, state TV reported, replacing the nations most prominent nuclear scientist with a UN-sanctioned minister who has no reported experience in nuclear energy but ties to the defense ministry. Irans newly elected hard-line President Ebrahim Raisi chose Mohammad Eslami, a 64-year-old civil engineer who previously oversaw the countrys road network, to lead Iran’s civilian nuclear program and serve as one of several vice presidents. He succeeds Ali Akbar Salehi, a US-educated scientist who was a key player during the years of intense international diplomacy that led to Tehrans now-tattered 2015 landmark nuclear deal with world powers. The deal curbed Iran’s nuclear activities in exchange for sanctions relief, but then-President Donald Trump unilaterally withdrew the United States from the agreement and reimposed crushing sanctions. Iran, in response, has gradually and publicly abandoned all restrictions on its stockpiles of low-enriched uranium. In 2008, when Eslami served as head of Irans Defense Industries Training and Research Institute, the United Nations sanctioned him for “being engaged in, directly associated with or providing support for Iran’s proliferation sensitive nuclear activities or for the development of nuclear weapon delivery systems.” The Associated Press said the UN linked the blacklisting to his "involvement in procurement of prohibited items, goods, equipment, materials and technology.” During the tenure of former President Hassan Rouhani, Eslami served as Transport and Urban Development Minister. Before joining the Cabinet in 2018, he worked for years in Irans military industries, most recently as deputy defense minister responsible for research and industry. He holds degrees in civil engineering from Detroit University of Michigan and the University of Toledo, Ohio.
