Ken Angielczyk focuses his research on the paleobiology of nonmammalian synapsids. His current research includes systematic and taxonomic work on dicynodont therapsids; investigation of Permian and Triassic dicynodont faunas from Tanzania and Zambia, with particular interest in their implications for the causes of and recovery from the end-Permian extinction; and research on how trophic network structure can facilitate or inhibit the spread of disturbances through a community. Other recent projects include morphometric investigations of factors that affect shell shape in extant turtles and skull shape in extant and fossil crocodiles.
