Samuel James is a researcher specializing in evolutionary biology, focusing on earthworm taxonomy. Samuel James, along with fellow researchers has described new species, such as Diplocardia Californiana[1], Diplocardia Woodi[1], Diplocardia Montana[1], and a new species related to the Giant Palouse earthworm[2]. Since January 2011, James has been working on phylogenomic investigation of the evolutionary history of Annelida, as part of the WormNet II: Assembling the Tree of Life for Annelida project[3], along with researchers Christer Erseus and Bronwyn W. Williams. He is currently part of the University of Iowa's Department of Biology, where he is an Associate Adjunct Professor.[4] Prior to the University of Iowa, James was a Research Associate at the University of Kansas, Biodiversity Institute, from 2003 until 2009.[3]
