Keith has worked all over the world as a field biologist, working primarily with seabirds and migratory songbirds. During this time Keith developed excellent statistical and spatial analytical skills that he has applied to a diversity of projects. Currently, Keith studies the ecology and genetics of a songbird with two migratory phenotypes that meet in a hybrid zone. During his tenure as a PhD student he enjoyed working in the field while further developing his modelling skills. Keith has a long history of collaboration with the Klamath Bird Observatory.
