Brian Weeks joined SEAS in 2019 as an assistant professor. He is an evolutionary ecologist who studies how bird species and bird communities have responded to environmental change. He is a museum-, field-, and lab-based biologist with interests ranging from the influence of macroevolutionary processes on the vulnerability of communities in the Solomon Islands to morphological changes over the past 40 years in North American birds. Brian got his PhD in 2017 at Columbia University, where he was also affiliated with the Department of Ornithology at the American Museum of Natural History.
