My interest is the relationship between morphology and function in the teeth of mammals. This includes: figuring out the functional principles of teeth and how morphology controls function, primarily through the application of engineering methods; measurement of functional aspects of real teeth from three-dimensional surface data of mammalian teeth; and three-dimensional modelling of hypothetical and existing tooth forms.
Most recently I have been examining questions relating to maximum body size in mammals, including global patterns of increase and maximum rates of evolutionary change.
I am an Australian Research Fellow in the School of Biological Sciences. From 2003 to 2008 I was a postdoctoral fellow with Mikael Fortelius and Jukka Jernvall in the Evolution & Development Lab in the Institute of Biotechnology, University of Helsinki. One of the main projects I am working on is the MorphoBrowser, an online browsable database of 3D tooth shapes.
