About Dr. Julia Boughner
Associate Professor, Anatomy & Cell Biology, University of Saskatchewan.
Ph.D. Anatomy, Department of Anatomy and Developmental Biology, University College London.
B.Sc. Biological Anthropology, Department of Anthropology, University of Toronto.
My research background is in physical anthropology, broadly, the study of primate biology and evolution. Over time I’ve morphed into an evolutionary developmental biologist and have worked with various model organisms, including mouse, chick and snake.
Perhaps because I am one, primates remain close to my scientific heart. While I use mouse models in much of my work, I typically ask scientific questions that I hope will inform some aspect of human evolution. In particular, I work to better understand primate craniofacial evolution and development.
Currently, I organize Café Scientifique-Saskatoon. Previously, I co-founded and co-organized one of the first Canadian Café Scientifiques in Vancouver, BC (est. 2004) with then fellow postdoc, Anne Mullin. In 2005, I created a home-grown science and technology radio show called “My Science Project” that aired on CiTR 101.9 FM UBC campus radio until 2008. Anne and I shared broadcasting duties as producers and hosts. In August 2009 I was fortunate enough to participate in the 2-week Science Communications Program at The Banff Centre. For me science outreach is both fun and crucial: I continue to be on the look-out for ways to fill the world with more science.
My laboratory’s principal research question is, “What underlies the coordinated development and evolution of the jaws and teeth?” We combine genetic, morphological, statistical shape analyses, and high-resolution image data to get at the mechanisms that coordinate pre- and postnatal developmental changes among faces, jaws and teeth. My research and expertise have been featured locally, nationally and internationally on the CBC Evening News, CBC Radio 2 Drive, The Star Phoenix, National Geographic, Gizmodo.com, Fusion.net, and HealthyDebate.ca, among other media outlets.
Evolutionary Developmental Biology of the Teeth and Jaws
As teeth and jaws grow they must fit together to work properly and allow an animal to eat. Because teeth sit within the jawbone, any developmental or evolutionary changes in jaw shape or size will invariably affect the teeth and vice versa. To understand how a body part develops is to understand how it may have evolved. It is not known how the timing of tooth and jaw development is coordinated such that these parts “fit” together properly during pre- and postnatal growth. With support from NSERC Canada, our current focus is to explain how the pace of tooth and jaw development has evolved to be (relatively) synchronous.
One option is that the timing of tooth development is controlled by signals from the jaw tissues, and vice versa. However, good evidence suggests that the opposite is true: the pace of tooth and jaw development has been naturally selected to run in parallel with no cross-talk between tooth and jaw tissues. We aim to tackle this research question using complimentary genetic, statistical and advanced 3D imaging data alongside mammalian models at various stages of pre- and postnatal development.
Being virtually next door to the Canadian Light Source (Canadian Light Source), home to Canada’s only Synchrotron, my lab has access to amazingly powerful high-resolution imaging technologies with which to study morphology. Supported by the Canadian Foundation for Innovation, we will soon have an Optical Projection Tomography scanning system (bioptonics), enabling us to image and measure embryonic morphology alongside the genetics driving this development. We are also fortunate to have the Computed-Tomography Facility at our department in Dr. Dave Cooper’s lab (Dr. Cooper's Lab).
The Master Plan
Our aim is to start to fill a fundamental gap in scientific knowledge by helping to explain how jaw and tooth development is coordinated in time. This insight should further clarify how teeth and jaws have developed and evolved such an amazing variety of different yet functional forms across living and extinct mammals. More broadly, this insight also speaks to how functionally-linked body parts develop and evolve in tandem.
