Senior Lecturer in Anatomy

During ontogeny, the jaws increase in size, housing a developing dentition that increases in size and number, and all the while the jaw is required to adequately resist the biomechanical demands of mastication. My research therefore explores the coordinated development and evolution of the dentition and jaws, and how this integration may constrain the development of the masticatory system. The research uses a wide variety of methods including finite element analysis (FEA) and geometric morphometrics, in vivo electromyography and jaw kinematics, CT imaging and histology.
