Introduction
I am a PhD candidate in the Integrative Anatomy program at the University of Missouri School of Medicine, Columbia, MO.
I study the functional morphology of the hip and pelvis in humans, primates, and early hominins, especially as it relates to understanding locomotor and ecological diversity in fossil hominins.
Additionally, I am interested in how anatomical variation contributes to symptoms and biomechanical differences in patients with conditions such as femoroacetabular impingement.

Accurate and repeatable assessments of three-dimensional (3D) skeletal morphology are critical to interpretations of vertebrate functional anatomy. In skeletal specimens, these goals can be accomplished using in-silico models derived from 3D laser scan, photogrammetry, or computed tomography (CT) data. Assessments of skeletal morphology in living s...
Original article: https://doi.org/10.17159/sajs.2019/5911 Due to an error in the reference plane, the elevation range shown for the digital elevation model (DEM) in Figure 5a is incorrect. The correct elevation range is 1629.41–1679.64 m. The DEM and orthomosaic map data were reprocessed using Agisoft Metashape 1.7.4. Processing parameters for the...
Hominin pelvic form differs dramatically from that of other primates by having more laterally facing iliac blades, a wider sacrum and a larger, transversely broad pelvic inlet. Acetabular orientation may differ as well, plausibly related to differences in load transmission during habitual bipedal posture and locomotion. Here, we test the hypothesis...
Isimila is a Middle Pleistocene archaeological site located in southern Tanzania. The site is known for large surface assemblages of later Acheulean lithics such as hand axes, cleavers, scrapers and cores. While hominin remains have yet to be discovered at the site, Isimila offers a unique window into Middle Pleistocene Homo behaviour. Although Isi...
The taxonomic identification of mammalian fauna within fossil assemblages is a well-established component of paleoenvironmental reconstructions. However, many fragmentary specimens recovered from fossil sites are often disregarded as they can be difficult to identify with the precision required for taxonomic methods. For this reason, the large numb...

Blomberg’s K for all measures.
Values > 1 suggest that phylogeny is driving the similarities between closely related species. Only values < 1 were used in our analysis.

Past bioarchaeological analyses of human remains from the Early Christian Period site of Kulubnarti, Nubia (550‐800 CE), have revealed differences in patterns of stress between two contemporaneous cemeteries (mainland [21‐R‐2] and island [21‐S‐46]) that are thought to represent separate socioeconomic groups. However, to this point, differences in a...
Abstract: Femoroacetabular impingement (FAI) is a clinical pathology of the hip resulting from repeated abutment of an abnormally shaped femoral head-neck junction with the acetabular rim. One form of FAI, the cam-type deformity, is thought to result from mechanical stress on the femoral head-neck junction during epiphyseal fusion and from intense,...
Located in the southern highlands of Tanzania, the Middle Pleistocene site of Isimila contains one of the most abundant Acheulean stone assemblages in Africa, if not the world. Although the extensive riverine erosional beds are littered with innumerable artifacts which include hand-axes, hammerstones, and flaked tools, few faunal remains have been...
For more than a century, the morphology of the femoral head-neck junction has been used as a tool to reconstruct activity in the archaeological record. More recently, the head-neck junction has become the focus of intense study in the clinical literature following the description of femoroacetabular impingement (FAI), an injury common in athletes t...

This project seeks to understand when and how femoroacetabular impingement (FAI) arose and how it may have affected ancient people, as well as what a better understanding of FAI in ancient populations can tell us about ancient their acitivity pattern. If we can better understand the evolutionary history of FAI, we may also be able to provide better treatment options and screening methods for FAI in modern patients.
