Christine Wall, Ph.D.

My research is primarily lab-based and focused on the biomechanics of mastication and incision.  I want to understand how feeding structures work and how variation in function is related to variation in form.  This information can then be applied to understanding the adaptive diversity of living and fossil animals.  To do this, I use in vivo methods to observe structures at work, and combine these observations with detailed morphological data and statistical analysis.  I am particularly interested in muscular, skeletal, and dental specializations to breaking down foods that differ in structural and material properties.  An important focus of this work has been to understand (1) the interactions between size and feeding biomechanics, (2) jaw and tooth movements during chewing and other feeding behaviors, and (3) the patterns of activation of the chewing muscles.  A recent research direction for the lab is to collect data on the energetic costs of feeding to generate links between what we know from lab-based studies about the morphology and physiology of the feeding apparatus and what we know from field-based studies about feeding ecology and diet.

As a Research Professor Emerita and through my work as a Senior Research Scientist at the Duke Lemur Center, I continue to be active in research and mentoring.
