In 1999, Gelia T. Castillo was conferred the rank and title of National Scientist by the President of the Philippines and is professor emeritus at the University of the Philippines Los Baños. All her professional life, she has been guided by the precept that science must serve a human purpose. She expounds on this, and on her special interest in rice, in several papers and lectures, posts in this blog, and in a Pioneer Interview.
Gelia served in several national and international boards and committees in agriculture and health and continues to be involved in some of these. Among her publications are four books: All in a Grain of Rice; Beyond Manila; How Participatory is Participatory Development?; and Rice in our Life.
