Nouriel Roubini (born 29 March 1959) is a professor of economics at the Stern School of Business, New York University and chairman of RGE Monitor, an economic consultancy firm.

After receiving BA in political economics at Bocconi University and doctorate in international economics at Harvard University, he began academic research and policy making by teaching at Yale while also spending time at the International Monetary Fund (IMF), the Federal Reserve, World Bank, and Bank of Israel. Much of his early studies focused on emerging markets. During the administration of President Bill Clinton, he was a senior economist for the Council of Economic Advisers, later moving to the United States Treasury Department as a senior adviser to Timothy Geithner, who is now Treasury Secretary.

In 2008, Fortune magazine wrote that: "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." In September 2006, he warned to 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." He also foresaw "homeowners defaulting on mortgages, trillions of dollars of mortgage-backed securities unraveling worldwide and the global financial system shuddering to a halt". The New York Times labeled him "Dr. Doom", whereas, in hindsight, IMF economist Prakash Loungani has called him "a prophet".
