Evolutionary Biology - Molecular phylogeny and population genetics of closely related birds to study speciation and character evolution. Recent research has focused on the orioles (genus Icterus), as well as ravens (genus Corvus). Current project on the conservation biology of the critically endangered Bahama Oriole. http://www.birdscaribbean.org/wp-content/uploads/2016/08/Omland-Bahama-Oriole-NAOCposter2016.pdf
Introductory biology, diversity, evolution, phylogeny, population genetics, animal behavior, conservation. Especially interested in teaching clear tree thinking as there is no "ladder of progress" in evolution.
