A petroleum engineer and private consultant, he is a member of the advisory boards of Riverstone-Carlyle and the Stanford Financial Group. He is also a member of the board of governors and special adviser to the chairman of the Centre for Global Energy Studies in London. Between September 2000 and September 2005 he was a nonexecutive director of Royal Dutch Shell.

In academia, he is a member of the advisory boards of the Institute for Latin American Studies at Babson College, the Energy Institute of the University of Houston, the Maguire Energy Institute at Southern Methodist University, and the Institute of Global Studies at the George Washington University.

Giusti began his career at Shell Corporation in Venezuela, after which, in 1976, he joined Maraven, S.A., an operating affiliate of Petróleos de Venezuela, S.A. (PDVSA). At PDVSA, he held diverse positions related to exploration and production, refining, corporate planning, and marketing, including serving as chairman from 1994 to 1999. Under his leadership, the Venezuelan petroleum sector underwent major reform, which included an opening to private participation, with resulting estimated foreign direct investments of about $30 billion for the period 1995 to 2004. Over the last five years of his tenure at PDVSA, the company continued to consolidate its international downstream position by completing major deals with Mobil, Phillips, Chevron, and Amerada Hess.

Giusti graduated in 1966 from the University of Zulia, Venezuela, and received an M.S. in petroleum engineering from the University of Tulsa, Oklahoma, in 1971. He is a member of the advisory boards of Energy Intelligence Group (publisher of PIW, Oil Daily, and Energy Compass) and the Inter American Dialog.
