About

I'm a biological anthropologist and I hold a faculty position in the College of Dentistry and an affiliation with the Department of Anthropology. I received my training at the University of Iowa, where I also did a postdoc. My background is in paleoanthropology and human variation. My research focuses on factors, genetic and enviornmental, which influence craniofacial growth and development. I am particularly interested in how obesity affects dental development and eruption - we know that obese children erupt their teeth at younger ages, but we don't know why. One of my current projects is examining whether increased oral inflammation may be associated with early tooth eruption in obese children.
