I have long been fascinated by morphological diversity, especially that exhibited by the vertebrate head. Variation in morphology has been critical to evolution, but is also a major contributor to disease. Therefore, understanding the origins and regulation of morphological diversity is critical to studies of both disease and evolution. My research addresses a fundamental question in developmental biology: how do developmental processes contribute to phenotypic variation and how does this variation contribute to disease and evolution of the jaw skeleton? Using both classical comparative embryology and modern high-throughput and embryological manipulation techniques, I investigate how variation in molecular and cellular mechanisms contribute to variation in phenotype. The overall goal of my research is to better understand how developmental and cellular processes produce phenotypic variation, and to identify key developmental changes involved disease and evolution of the jaw.

Schneider   “For every type of animal there is a most convenient size, and a large change in size inevitably carries with it a change of form.” Haldane 1926.   As articulated most eloquently by Haldane (1926) in his classic essay on “Being the Right Size”, every animal[…]
