School roles and responsibilities
Director of the Animal Postcranial Evolution (APE) Lab.
I am a palaeoanthropologist who studies the functional morphology of the wrist and hand in extant and fossil primates. My research focuses on extant and fossil apes, including fossil hominins, to further our understanding of the origin of human bipedalism and hand use throughout our evolutionary history. I aim to understand the relationship between bone shape and function of the hand through analyses of ontogeny, internal (trabecular and cortical) bone structure, and the biomechanics of primate locomotion. My current research interests include:
- Functional morphology of the Homo naledi and Australopithecus sediba hands
- Trabecular and cortical bone structure in extant and fossil primate hands to better understand locomotion and tool-use in early hominins
- Biomechanical analyses of terrestrial and arboreal locomotion in apes
- Functional morphology of fossil hand bones of Miocene hominoids
I received my PhD from the University of Toronto, working on the developmental morphology of the ape wrist and the origin of human bipedalism. Before coming to the University of Kent, I was a Research Associate, teaching human gross anatomy at Duke University (2007-2009) and was postdoctoral Junior Researcher at the Max Planck Institute for Evolutionary Anthropology (2009-2013). I have participated in palaeontological field excavations at Miocene sites in Hungary as well as Plio-Pleistocene sites in South Africa.back to top

I occasionally teach on undergraduate (e.g. SE 302) and graduate (e.g. SE856) modules, but will not be teaching full time until September 2020.back to top

Director of research on Australopithecus sediba hand fossils: Investigation of Au. sediba and Rising Star hand remains from South Africa in collaboration with Lee Berger and Job Kibii (University of the Witwatersrand) and Steve Churchill (Duke University).
Fossil hominin and hominoid hand use: Comparative investigation of fossil hominin (australopiths to Neandertals) and Miocene hominoid hand remains using morphometric and micro-CT data. This research aims to shed light on locomotor and tool-use behaviours throughout the evolution of the human lineage. Collaborators: Matthew Skinner (UCL), Steve Churchill (Duke University), David Begun (University of Toronto).
Functional signals in trabecular and cortical bone structure: A comparative investigation of internal bony morphology of the primate hand to assess variation in joint loading patterns and how this reflects differences in locomotor and manipulative behaviours. Collaborators: Matthew Skinner (UCL), Dieter Pahr and Thomas Gross (Vienna University of Technology), Huynh Nguyen and Jean-Jacques Hublin (Max Planck Institute-EVA) and Richard Lazenby (University of Northern British Columbia).
Biomechanics of primate locomotion: Investigation of variation in biomechanics of terrestrial and arboreal locomotion in apes as well as other primates, including the aye aye, in both captive and natural settings. Collaborators: Daniel Schmitt and Brian Hare (Duke University) and Roshna Wunderlich (James Madison University).back to top
I can offer supervision of PhD and MA/MSc research within any of my areas of interest – functional morphology of the postcranial skeleton, including external and internal (using microCT data) bony morphology – with a particular focus on the upper limb.

Physical Anthropology Women’s Mentoring Network (PA WMN), an organization that brings together more senior women in biological anthropology with younger women seeking advice as they transition from their PhD to a postdoc, to their first academic positions and through the tenure process, balancing work, research and family. We organize mentoring events at the American Association of Physical Anthropology (AAPA) conference each year, but offer mentoring year round. I currently sit on the Steering Committee and was Chair of PA WMN in 2011-2012.back to top
I am available to provide commentary or discussion on human or nonhuman primate evolution, primate locomotion, or skeletal morphology and evolution.
