Guillermo Castilleja distinguished alumni yale fes
Guillermo Castilleja ’83 M.F.S., ’91 Ph.D. has been described as a “true systems thinker,” something he says he developed during his time at F&ES working under F&ES Prof. Herb Bormann. Systems thinking, Castilleja says, has been key in his work both as a scientist and in his current role as senior fellow at the Gordon and Betty Moore Foundation where he oversees strategy and serves as special advisor to the president. Previously, he was chief program officer of environmental conservation initiatives, which account for the lion’s share of the $6.5 billion private foundation.

Castilleja is also chair for the Global Alliance for the Future of Food and on The Economics and Ecosystems of Biodiversity Advisory Board and the boards of the Climate and Land Use Alliance and the Fondo Mexicano Para La Conservación De La Naturaleza, A.C./Mexican Fund for the Conservation of Nature, A.C.
