My research focuses on reconstructing dental development using incremental markers in dental hard tissues. I utilize polarized light microscopy to reconstruct the timing of dental development, which correlates with important life history variables such as weaning and first reproduction. I am currently working on a variety of mammals, from modern humans and nonhuman primates to extinct elephants. I am also working on several 55 million year old fossil species, including some of the earliest primates.
