External Advisory Council

zeiglerRobert Zeigler - Chair

Dr. Robert "Bob" Zeigler is an internationally respected plant pathologist with more than 30 years of experience in agricultural research in the developing world. Bob's professional life spanned Africa, Latin America, US, and Asia. He has had a productive research career on diseases of rice that focused on host-plant resistance, pathogen and vector population genetics, and their interactions to develop durable resistance and sustainable disease management practices. As Bob's career moved increasingly towards research management his interests expanded to include broader crop management issues, the social forces shaping the agricultural environment, and finally the economic and political arena that frames food security and poverty issues. He has published over 100 scientific works in these areas and often serves as an expert resource on rice security in the regional and global media.
