Sefako Makgatho Health Sciences University (SMU) is leading advancements in medical research and innovation, identifying globally significant themes with societal impact. Central to this mission is Professor Anna Oettlé, a Full Professor in the Anatomy and Histology Department, whose exceptional contributions to anatomical research have earned her a prestigious accolade at the Vice-Chancellor’s Excellence Awards 2024.
Oettlé qualified as a medical doctor at the University of the Witwatersrand in 1988 before pursuing an MSc in Anatomy with distinction. Transitioning into academia in 2002, she developed a keen interest in anatomical variations, which ultimately earned her an NRF C2 rating. “Clinical practice revealed the significance of anatomical variations in diagnosis and treatment. Modern 3D imaging techniques enhance visualisation, yet the principle of using multiple views remains essential,” she explains.
Oettlé’s research has evolved from traditional anatomical studies to advanced 3D imaging techniques. A landmark achievement in 2009 saw her collaborate with the South African Nuclear Energy Corporation (Necsa) to conduct the first cone beam tomography scans on human remains, revolutionising 3D anatomical analysis.
Her research spans bone and dental variation, craniofacial morphology, hominin evolution, and forensic applications. Notably, her work in biological profiling methods aids forensic scientists in identifying unknown victims, significantly contributing to criminal investigations.
The significance of an NRF Rating
An NRF rating validates a researcher’s contributions, enhances visibility, and unlocks funding opportunities. “Applicants must present five publications over eight years. A C2 rating confirms that all reviewers recognise the researcher as established, with impactful contributions and international collaborations,” she notes.
At SMU, institutional support has been invaluable. “SMU provides expert consultants to review applications and offer constructive feedback. Since joining in 2017, this environment has been instrumental in increasing my research productivity.”
Among her most cited studies is one that established an age classification system from sternal rib ends for South Africans, widely used in forensic profiling. “This study has been cited 143 times, assisting biological profiling. Similarly, our research on the mandible’s microstructure has crucial applications in orthodontics and forensic science,” she says.
Her research directly benefits medical practice, enabling clinicians to assess cephalopelvic disproportion during childbirth and inform dental procedures. It also equips forensic scientists with localised standards for facial reconstruction in missing persons cases.
Oettlé champions mentorship and interdisciplinary collaboration. “Engineers have helped refine 3D measurement techniques. Cross-disciplinary work fosters innovation. I mentor early-career researchers, believing in their potential and encouraging impactful work.”
She emphasises the role of NRF ratings in strengthening SMU’s research reputation. “These ratings drive early-career researchers to focus and secure funding. Increased funding facilitates mobility and international collaboration.”
Looking ahead, she aims to expand 3D scanning applications and enhance biological profiling methods. “3D imaging is becoming more accessible. My goal is to secure funding for advanced equipment and foster interdisciplinary collaborations.”
Reflecting on her VC Excellence Award recognition, she states: “It is an honour and a motivator to continue publishing. Previous awards funded research assistants to archive skeletal remains. I plan to use this funding to archive our scan collection at SMU’s central archives for future research.”
Encouraging aspiring researchers, she advises: “Dream big, work hard, and embrace new ideas. Stay positive and seek collaboration. Almost anything is possible with dedication.”
As SMU continues to drive medical research and innovation, its commitment to fostering excellence and collaboration ensures a lasting impact on healthcare. Through dedicated researchers like Oettlé, SMU is shaping the future of medical science, making transformative contributions to global healthcare.
