Dr. Jack Gibbons, the President's science advisor and the director of the Office of Science and Technology Policy, announced late last week that he will resign effective March 15. Dr. Neal Lane, the director of the National Science Foundation (NSF), has been nominated by President Clinton to replace Gibbons. Replacing Lane at NSF will be Dr. Rita Colwell, the president of the University of Maryland Biotechnology Institute. Colwell was nominated earlier this year to become deputy director of NSF. Indications are that Dr. Joseph Bordogna, who has been acting deputy director, will continue in that capacity for the near term.
