I am essentially a comparative vertebrate embryologist, with broad interests in ecological and evolutionary questions. My current research aims to test whether processes during organ development can bias the production of variation (the phenotypes that are available for natural selection in a population) and thereby influence evolutionary patterns. I work on organ-systems with repeated elements that can vary in size; organs such as teeth or finger bones form in sequence from a single initial condensation, and, among species, there is significant variation in sizes. To test ideas and advance theory in this area, I employ methods from experimental embryology, comparative anatomy, developmental genetics, and computational modeling.

I also have a great interest in observing evolutionary and developmental processes in situ, that is, in nature and in response to ecological variation, and thus I study “natural evolutionary experiments” on populations of fishes. In these studies, I am focusing on interactions of developmental temperature and evolution of growth rates and tissue differentiation rates.

I welcome students and postdoctoral researchers who are interested in these research questions to contact me.

Current Projects

  • Developmental bias in the variational properties of phalanges (finger and toe bones) in birds and other vertebrates, with the chick as an experimental model.
  • Microevolutionary trade-offs in axial skeletal and muscle growth and development in populations of fishes along latitudinal or temperature gradients.
