Biological anthropology, forensic anthropology, modern human variation, growth and development, ancestry.


My research focuses on the identification of subadults through the creation and development of age and sex estimation techniques and the impact of population structure on the pattern of modern human variation.

Most of my current research seeks to explore the predictive ability of age and sex indicators and to develop techniques to accurately identify unknown decedents. Federal funding was awarded from the National Institute of Justice (Award 2015-DN-BX-K009) and National Science Foundation (NSF BCS-1551913) to improve subadult age and sex estimation techniques. The projects use thin-slice computed tomography scans acquired from a large, diverse sample of modern subadults (ages birth to 20 years) to develop age and sex estimation techniques. We are collecting epiphyseal appearance and fusion data, long bone breadths and lengths, dental development, and pelvic landmark coordinates. The current NIJ and NSF projects, and my previous research, has resulted in two freely available graphical user interfaces (KidStats and KSCollect) to increase the applicability of methods for forensic anthropologists and promote collaboration.

I am also interested in the craniometric and postcraniometric variation in genetically admixed populations, especially in South Africa. Current research is dedicated to exploring the sex-biased asymmetry in the craniometric variation of modern South Africans. I am associated with numerous colleagues and projects concerning in-depth assessments of population variation and sexual dimorphism within South Africans. Most of the research focuses on the micro-evolutionary changes in the population and the direct effects of population history, migration and sociopolitical regimes.

I am a member of the American Association of Forensic Sciences, American Association of Physical Anthropologists, and Anatomical Society of Southern Africa. I also consult on forensic anthropological cases and/or outdoor recoveries.
