Nouriel Roubini is a Persian American professor of economics at New York University's Stern School of Business and chairman of Roubini Global Economics, an economic consultancy firm.

Roubini's critical economic views have earned him the nicknames "Dr. Doom" and "permabear" in the media. In 2008, Fortune magazine wrote, "In 2005 Roubini said home prices were riding a speculative wave that would soon sink the economy. Back then the professor was called a Cassandra. Now he's a sage". The New York Times notes that he foresaw "homeowners defaulting on mortgages, trillions of dollars of mortgage-backed securities unraveling worldwide and the global financial system shuddering to a halt". In September 2006, he warned a skeptical IMF that "the United States was likely to face a once-in-a-lifetime housing bust, an oil shock, sharply declining consumer confidence, and, ultimately, a deep recession". Nobel laureate Paul Krugman adds that his once "seemingly outlandish" predictions have been matched "or even exceeded by reality."

As Roubini's descriptions of the current economic crisis have proven to be accurate, he is today a major figure in the U.S. and international debate about the economy, and spends much of his time shuttling between meetings with central bank governors and finance ministers in Europe and Asia. He has appeared before the US Congress, the Council on Foreign Relations, and the World Economic Forum at Davos.
