Joe Tucci is Chairman of the Board of Directors, President and Chief Executive Officer of EMC Corporation. Tucci has been EMC's Chairman since January 2006 and President and CEO since January 2001, one year after he joined the company as President and Chief Operating Officer. Since his arrival at EMC, Tucci has led EMC through a period of dramatic revitalization, continued market share gains, and sustained double-digit growth. He has transformed EMC's business model from what was a near exclusive focus on high-end storage platforms to what is now the industry's most comprehensive portfolio of best-of-breed platforms, software, services, and solutions that enable organizations to implement information lifecycle management, aligning their IT infrastructure with their business based on the changing value of their information. Today, EMC operates with a balanced product portfolio in which software and services generate more than 50% of its annual revenues and hardware less than 50%. EMC has evolved with its market from an information management and storage company to a provider of open information infrastructure. Concurrently, he has spearheaded the investment of more than $4 billion (since 2003) in strategic software acquisitions aimed at filling out EMC's product portfolio, entering new market segments, and expanding the company's addressable market opportunity. Over this period he has strengthened EMC's management team with the integration of executives from other major technology companies.

Acknowledging EMC's rejuvenation, the editors of Business Week named Tucci one of Corporate America's best senior managers of 2004. Before joining EMC, Tucci directed the financial and operational rebirth of Wang Global during six years as its Chairman and CEO.

Under his leadership, Wang acquired and integrated ten companies from 1995 through 1999, and its market capitalization more than tripled. In June 1999, Wang was acquired by Getronics NV. Prior to joining Wang in 1990, Tucci was President of U.S. Information Systems for Unisys Corporation, a position he assumed after the 1986 merger of Sperry and Burroughs that created Unisys.
