Yuri Tsolakovich Oganessian (Russian: Ю́рий Цола́кович Оганеся́н, Armenian: Յուրի Ցոլակի Հովհաննիսյան; born 14 April 1933) is a Russian nuclear physicist of Armenian descent. Oganessian is considered the world's leading researcher in superheavy elements. He and his team discovered the heaviest elements in the periodic table.
At age 28, he joined the group of Georgy Flyorov (Flerov) at the Joint Institute for Nuclear Research in Dubna.
Oganessian is the scientific leader of the Flerov Laboratory of Nuclear Reactions (FLNR). He invented cold fusion in one-atom-at-a-time nucleosynthesis (not related to the similarly-named pseudoscientific claims) around 1970 and pioneered hot fusion in the late 1990s. In 2009, scientists in the United States confirmed Oganessian's team's discovery of flerovium over a decade before. He is a researcher in islands of stability. He continues to search olivine in pallasites hoping to find superheavy elements (or their fission tracks) in nature.
In November 2016, IUPAC announced that element 118 be named oganesson to honor Oganessian. Prior to this announcement, a dozen elements had been named after people, but of those, only seaborgium was likewise named while the person (Glenn Seaborg) was alive.
