Thesis title: Ancestral variation in mid-craniofacial morphology of a South African sample
Supervisor: Dr Jacqui Friedling
Thesis description: Ancestry estimation remains crucial in a medico-legal setting as the likelihood of victim identification can be significantly improved by an accurate estimation of ancestry. Due to the high crime rate in South Africa, it is essential that an accurate demographic profile be constructed to prevent a backlog of cases and ensure that justice is served. Numerous studies have identified the cranium; specifically the mid-facial region, as the most accurate element in ancestry estimation. Currently, no South African studies have assessed ancestral variation in shape and size in the mid-facial region of cranium. Therefore, the current study aims to assess ancestral variation mid-craniofacial morphology in a skeletal sample of South Africans of African, European and Mixed ancestry. The study will assess nonmetric, anthroposcopic, metric and geometric morphometric techniques to determine which technique is most accurate in estimating ancestry in a South African sample.

Thesis Title: TBD (Dental wear analysis of Khoesan foragers and pastoralists in southern Africa)
Supervisor: Dr. Victoria Gibbon; Co-supervisor: Dr. Deano Stynder (Department of Archaeology, University of Cape Town)
My proposed research will pursue temporal and spatial analyses of dental wear and pathology in Later Stone Age (LSA) hunter-gatherers and foragers to examine diet and cultural practices. This will provide context and further insight into the assemblages I will be examining, attention will be paid to cultural, environmental, subsistence, and demographic patterns – and potential developments in these spheres over time. In examining wear quantity and direction, as well as looking for patterns associated with subsistence strategies I hope to distinguish the variability between foragers and pastoralists, and coastal and non-coastal populations.

Thesis title: Axillary Web Syndrome (AWS) after treatment for breast cancer: a correlation of clinical variables with imaging data focussing on fascial changes before and after physiotherapy treatment.
Supervisors: Dr. Delva Shamley and Dr Charles Slater
Thesis description: Breast cancer is the most commonly diagnosed malignancy in women. Treatment complications of breast cancer occur frequently and can significantly impact patients’ quality of life. One such complication – Axillary Web Syndrome - presents as tight axillary cords, is painful and limits range of shoulder movement (ROM). This project looks into understanding the anatomical basis for this syndrome, focussing on how disruption of fascia, as a three-dimensional connective tissue network, can explain these symptoms. Utilising ultrasound and MRI imaging pre- and post-physiotherapy, we are correlating qualitative information to quantitative measurements of pain, ROM and treatment variables to learn more on how to prevent this syndrome, inform clinical practise and improve these women’s quality of life in the future.

Thesis title: The effect of clothing on the decomposition process and post-mortem interval estimation in the temperate southwestern Cape, South Africa
Supervisor: Dr Victoria Gibbon Co-Supervisors: Dr Jacqui Friedling & Devin Finaughty
Thesis description: The estimation of the time-since-death or post-mortem interval (PMI) is a crucial element of forensic death investigations, and is influenced by multiple factors. Despite recent taphonomic studies in Cape Town, the effect of clothing on the general decomposition process remains largely unknown. Baseline data on decomposition rate has been established previously with unclothed pigs by this division in the forensically relevant Cape Flats Dune Strandveld habitat. I seek to determine the effect of clothing on limiting vertebrate and invertebrate access, to alter the rate of decomposition which may consequently affect the estimation of PMI. Most recovered individuals in forensic cases are clothed, highlighting the need for this research to understand the accuracy of PMI estimates and improve identification rates.

Thesis title: Geometric morphometric analyses to assess the accuracy of the zygoma for estimating ancestry in a South African population
Supervisor: Dr. Victoria Gibbon; Co-Supervisor: Elizabeth Dinkele, & Calvin Mole
Thesis description: Ancestry estimation is imperative in medico-legal investigation in constructing demographic profiles to aid in victim identification. In South Africa, high murder rates correspond to a high number of unidentified people. Thereby, increasing the caseload of unsolved cases; inhibiting family member’s receipt of closure and social justice. There is a need to ensure that ancestry estimation standards are relevant and reliable, as the South African populations is considered as a diverse population with complex and variable admixture. Some studies have utilised metric and non-metric methods, however, these have their limitations in estimating ancestry. Various studies have identified the mid-facial region of the cranium, as the most accurate element in ancestry estimation. Geometric morphometric research pertaining to ancestral variation in South Africa has focused on nasal aperture, orbit and craniofacial shape, albeit none have assessed variation in the zygomatic region of the cranium in South Africans of different ancestries. In the current study, geometric morphometric analyses will be used to assess variation in the zygomatic bone among African, European and Mixed ancestral groups.

Thesis Title: Optimisation of DNA Extraction from Teeth Submerged in Seawater in False Bay, South Africa
Supervisor: Dr. Victoria Gibbon
Co-supervisor: Ms. Laura Heathfield (Division Forensic Medicine and Toxicology, Department of Pathology)
Thesis description: DNA is currently the gold standard in confirming the identification of an unknown individual. Identification of decomposed, burnt or skeletonised remains is problematic; particularly in cases where the environmental effect on the decomposition of these bodies is not well known. Salt River mortuary in Cape Town, frequently receives cases of human remains washing up along the city’s coastline. In these cases identification is difficult due to limited research on the taphonomic influence of the sea. In addition, extracting sufficient quantities of good quality DNA has been problematic, if not impossible. Therefore, it’s the goal of my research to answer whether DNA can be extracted from teeth that have been submerged in seawater over a period of time. My project forms a part of a larger research project that is studying decomposition in the sea environment of False Bay, Cape Town. In my study teeth will be extracted from pigs (Sus Scrofa) and undergo tooth preparation and DNA extraction to demonstrate a proof of concept. Teeth are being used in this study as they provide a protective encasing, which protects the DNA from environmental degradation If, I find that DNA can be extracted, these findings will feed into and necessitate further research by applying the developed methods onto a human model.

Thesis title: Scaling of the thoracic and lumber vertebrae size to overall body size: vertebral dimensions in a modern South African sample.
Supervisor: Professor Graham Louw
Thesis description: this project seeks to examine the relationship that exists between body size (represented by body weight) and vertebral size (represented by vertebral height and area), with special attention given to the lumbar vertebrae which form the major weight-bearing elements of the axial skeleton. This relationship is important because it can help researchers understand why small vertebral size is a risk factor for vertebral fracture, it can help to predict which vertebrae of a specific region of the spine are most likely to fracture and finally, this relationship can help researchers better understand the relationship between obesity and low back pain. The latter is very important since recent data on the global and regional trends on overweight and obesity indicate that South Africans have the highest rate of overweight and obesity throughout the Sub-Saharan region, with females having the highest percentages when compared to their male counterparts. This trend of high overweight and obesity rates in South Africa, coupled with recent unpublished data indicating that South African women have absolutely and relatively smaller vertebral dimensions (height and area) compared to males, has the potential to negatively affect lumbar column loading, especially during postmenopausal life. The relationship between vertebral size and overall body size also has the potential to change the way certain skeletal modifications such as vertebral osteophytosis are viewed, i.e., challenging the conventional view that their presence indicates "wear and tear" over time, but rather an adaptation to relatively small vertebral size. The project looks at what happens to vertebral size in persons with different body sizes (ranging from severely thin individuals to overweight individuals, as indicated by their BMI's, calculated from recorded cadaveric weights and heights).
