Biographical Sketch

Dr. Meldrum joined the ISU faculty in 1993, after a stint with Northwestern University. His research revolves around questions of vertebrate evolutionary morphology, especially primate locomotor adaptations. His formal study of primates began with doctoral research on terrestrial adaptations in African primates, and has since taken him from the dusty skeletal cabinets of far-flung museums to the remote badlands of Colombia and Argentina in search of fossil New World primates. He has published extensively on the evolutionary history of the South American primates and has described several new extinct species. He has documented varied primate locomotor specializations in laboratory and semi-natural settings. More recently his attention has returned to the emergence of modern human bipedalism. His co-edited volume, From Biped to Strider: the Emergence of Modern Human Walking, Running, and Resource Transport, proposes a more recent innovation of modern striding gait than previously assumed. As the acting director of the Center for Motion Analysis and Biomechanics (CMAB) he is collaborating with engineering faculty, paleontologists, and the Idaho Virtualization Lab, to model the pattern of evolution of the hominid foot skeleton. His interests also encompass the evaluation of the footprints purportedly left by an unrecognized North American ape, commonly known as Sasquatch. He has authored an expanded companion volume to the very successful Discovery Channel documentary, Sasquatch: Legend Meets Science. He edits the online refereed journal The Relict Hominoid Inquiry.
