Zeresenay Alemseged Dr. Alemseged's research program focuses on the discovery and interpretation of hominin fossil remains and their environments with emphasize on fieldwork designed to acquire new and much needed data on early hominin skeletal biology, environmental context, and behavior.

Andy Herries Dr. Herries co-directs excavations at a number of Early Pleistocene to Holocene sites with Darren Curnoe (UNSW). In the Northern Cape of South Africa, he is excavating a series of Later Stone Age rockshelters and Middle Pleistocene archaeological and fossil bearing localities. Along with Australian colleagues, he is conducting detailed multi-disciplinary comparative dating studies on these deposits using C14, U-series and ESR methods. Much of his work deals with exploring, sampling and excavating logistically challenging sites. At Pinnacle Point in South Africa, he runs excavations at the Middle Stone Age site of Cave 9 as part of the SACP4 project directed by Prof. Curtis Marean (Institute of Human Origins.)

Figure 7. Multi-dimensional model of anthropogenic alteration at Pinnacle Point Cave 13b (~90-180 ka) using magnetic mineralogy of cave sediments. Large spheres represent in situ hearths, small spheres the spread of anthropogenically altered material into the deposits and the very small spheres indicates no anthropogenic alteration and so areas not utilised by humans within the cave. (Modelling by Erich Fisher, University of Florida). Figure 8. Complex magneto-biostratigraphic studies of the Paranthropus bearing Gondoiln Palaeocave in South Africa, undertaken with Justin Adams, Glen Conroy and Kevin Kuykendall (Herries et al, 2006 [JHE]; Adams et al., 2007 [QSR]).

Susan Larson Dr. Larson's research focuses on the functional interpretation of musculoskeletal morphology of humans and nonhuman primates. Most of her work involves using laboratory methods to test hypothesized form/function relationships in order to more confidently reconstruct the behaviors of extinct primate species.

Figure 1. At the Indonesian Centre for Archaeology (ARKENAS) in Jakarta: I have recently had the opportunity to analyze the upper limb elements of the recently discovered diminutive hominin, Homo floresiensis, from the Island of Flores in Indonesia. Figure 2. Video-grabbed images of a baboon research subject walking on a branch showing raw EMG of its forearm rotator muscles to demonstrate how their recruitment is coordinated with tail motions to help the subject maintain balance (figure from Larson and Stern, 2005).

Fredrick Kyalo Manthi Dr. Manthi's main research interests are in the analysis of Pliocene and Pleistocene micromammals from Africa and their implications for reconstructing paleoenviroments during the course of hominid evolution.
