Steven E. Koonin, chief scientist for BP in London, gave an address titled "Energy, Environment, Security: Can We Have It All?" at 4 p.m. Monday, Feb. 4, in the Frances C. Arrillaga Alumni Center.

The talk, free and open to the public, was this year's Drell Lecture, hosted by Stanford's Center for International Security and Cooperation in the Freeman Spogli Institute for International Studies.

In 2004, Koonin joined BP, one of the world's largest energy companies, as group chief scientist. He is responsible for the company's long-range technology plans and activities, particularly those "beyond petroleum." His purview also includes BP's major university research programs around the world, and he provides technical advice to BP's senior executives.

The annual Drell Lecture, named for CISAC co-founder Sidney Drell, professor emeritus at the Stanford Linear Accelerator Center, and endowed by Albert and Cicely Wheelon, traditionally addresses a current, critical national or international security issue with important scientific or technical dimensions. Previous Drell lecturers have included New York Times correspondent Thom Shanker; the Rev. J. Bryan Hehir, a Harvard professor; Mohamed ElBaradei, director-general of the International Atomic Energy Agency; physician Margaret Hamburg; astronaut and Stanford alumna Sally Ride; and physicist Freeman Dyson.
