Interests/Description:

Biogeographer Mitchell Power holds a split position at the University of Utah with partnerships between the Natural History Museum of Utah and the Department of Geography.  His interests include botany, paleoecology, biogeography, fire history, and paleoclimatology. As Curator of the Garrett Herbarium, Mitchell has been investigating the history of vegetation and the role of fire during the past several thousand years in the western United States and other regions of the globe.  Mitchell studies fossil plant material preserved in sediment cores from lakes and meadows across the West and in tropical South America.   Mitchell has been an invited speaker at several international meetings including; the International Quaternary Association Paleofire meeting in Berne, Switzerland, the International Geosphere Biosphere meeting in Cape Town, South Africa and has been a member of the scientific steering committee for the Global Palaeofire Working Group and a co-chair of the International Multiproxy Paleofire Database.   His recent work explores the paleoclimate and disturbance history of tropical Amazonia with recent publications focusing on environmental change before and after the “Colombian Encounter,” when Europeans began to settle the New World during the 15th and 16th centuries.
