Sillett is part of an interdisciplinary group of researchers who conduct extensive monitoring of bird demography and environmental conditions. This work is unique in North America in both its duration and intensity. Sillett helped pioneer the study of bird populations throughout the annual cycle and was the first to demonstrate that global climate cycles and mortality during migration affect population dynamics. His research also explores how conservation and habitat restoration can benefit from understanding how humans have shaped biodiversity over thousands of years.
Sillett earned a B.A. from the University of Arizona in 1989, a M.S. from Louisiana State University in 1992, and a Ph.D. from Dartmouth College in 2000. He was a postdoctoral scholar at the U.S. Geological Survey’s Patuxent Wildlife Research Center from 2000 to 2001. Sillett joined the Smithsonian Migratory Bird Center in 2002.
In his spare time, Sillett enjoys bird watching, hiking, traveling, fishing, astronomy and reading science fiction and history. He lives in Takoma Park, Maryland, with his wife.
