Michael Dillon

Curator Emeritus

Integrative Research Center
Systematics/Phylogeny

Michael Dillon was Curator of Flowering Plants at the Museum for 30 years until his retirement in 2008. Over those three decades Dillon became one of the world’s leading experts on the plants of Peru, as well as the effects of El Niño events on neotropical plant populations.  He has published more than 100 scientific papers, and described dozens of new species, principally plants of Peru and Chile. Between 2005 and 2008 Dillon was Chair of the Department of Botany, overseeing a major upgrade of The Field Museum Herbarium and botanical labs (supported by the Searle Foundation), and spearheading pioneering efforts in collections digitization (supported by the National Science Foundation and the Mellon Foundation) that continue today.

With National Geographic Society and National Science Foundation financial support, Dillon with his Peruvian and Chilean colleagues has conducted botanical inventories in a wide variety of habitats, including the Atacama and Peruvian coastal deserts, montane forests, high jungle forests (selva alta), and high-elevation páramos.  During these many projects, Dillon has been a close collaborator and mentor to many South American colleagues, fostering scientific discovery and teaching generations of scientists in Peru and Chile. In recognition of his collaborations and contributions Dillon has been named honorary professor at four Peruvian universities.  In 2001, the Universidad Nacional de San Agustín launched a scientific journal in his honor—Dilloniana.  In 2013 a group of colleagues in Arequipa, Peru created a new research institute, “Instituto Científico Michael Owen Dillon" (IMOD) (http://www.imod.org.pe/), dedicated to interdisciplinary studies of biodiversity, and to improving the Peruvian peoples’ quality of life through the appropriate use of natural and cultural resources. 

 

Colleagues have named over a dozen species of plants in his honor and his collections have served as types for many more species new to science. Although nominally retired, “Dillon of the Andes” (as he was dubbed by colleagues at the Smithsonian in 2001) continues to conduct fieldwork and publish.

Accomplishments

Andean Botanical Information System

The Andean Botanical Information System (ABIS) presents information from floristic and systematic investigations of the flowering plants (phanerogams) of Andean South America. Topics include selected geographic regions and groups of Andean plants, flora of coastal Peru and Chile, floristic inventories from a variety of habitats in northern Peru, bibliographic resources, and searchable databases. Site launched in 1994.
