Biography

I am a biological anthropologist and Postdoctoral Fellow in the in the Function, Evolution and Anatomy Research (FEAR) Lab. My primary research interests focus on feeding adaptation in fossil hominins, modern humans, and non-human primates. I use a variety of experimental and quantitative techniques to address questions related to the evolutionary nature of: (1) dental and craniofacial variation in fossil hominins and living primates, including modern humans; (2) primate dietary ecology and feeding behaviour; and (3) primate biogeography. Methods I employ to investigate the questions that drive my research include finite element analysis, dental topographic analysis, in vitro bone strain analysis, shape analysis, and mechanical testing of primate foods. Additionally, I am interested in the impact of dietary resource competition on primate community structure, primate conservation biology in the Guiana Shield, and the cranial mechanics of non-primates mammals.

Qualifications

  • Ph.D. in Biological Anthropology, University at Albany, State University of New York (2015)
  • M.A. in Biological Anthropology, Stony Brook University, State University of New York (2009)
  • B.A. magna cum laude, Anthropology (Honors), Stony Brook University, State University of New York (2006)

Teaching Areas

In addition to the ZOOL100 unit (Principles of Zoology) here at UNE, I have experience teaching a number of subjects, including biological anthropology, human evolution, and human anatomy and physiology.

Research Interests

  • Feeding biomechanics and dietary adaptation in living and extinct primate species
  • Evolution of modern human craniofacial form
  • Primate feeding ecology and behaviour
  • Primate community structure
  • Primate conservation biology
