Albertus Engelbrecht: Lecturer in Singing and Coordinator of Vocal Studies at the Odeion School of Music.

The University of the Free State (UFS) is gearing up to honour a new group of graduates during the upcoming graduation ceremonies on 7-8 December 2023. Among the distinguished individuals set to grace the stage is Albertus Engelbrecht, Coordinator of Vocal Studies at the Odeion School of Music and an internationally recognised opera singer with a career spanning over two decades.

Engelbrecht has achieved a significant milestone, completing his PhD thesis titled “The Journey of a Versatile Singer”. On 7 December 2023, he will formally receive his qualification, marking the culmination of a seven-year academic journey. Reflecting on this achievement, Engelbrecht expressed his relief, stating, “It’s all still so surreal, but I think that the moment I walk onto that stage, then, will it only sink in.’’

The journey of a versatile singer

His thesis is an auto-ethnographic study that delves into the preparation and performance of five different styles and genres of Western art music. This unique approach includes a practical component, as he actively participated in five different concerts or performances, ultimately contributing to his research. He shared his motivation, stating, ‘’I was investigating how it would be possible to sing different kinds of Western art music styles and genres. The idea came from my professional experience, where I found that to become a successful opera and concert singer, it’s better for one to be able to do different styles and genres.’’

Looking ahead, Engelbrecht envisions his research making a meaningful impact on the development of emerging singers. He aspires to shape the future of vocal education, stating, “I hope that my contribution leads to new knowledge not only for singers but for their teachers and vocal coaches. This is so that they can approach music in the way it is written, and to find ways which make the music speak the best way it can. In this way, singers can be more versatile.’’

Future plans

Post-graduation, Engelbrecht has ambitious plans to further his growth within the industry. Expressing his goals, he said, ‘’I would like to grow not just as a performing artist but as a researcher too.” Currently collaborating with his former supervisor on a research project focusing on performance analysis, Engelbrecht aims to delve deeper into the research aspect of his profession. Additionally, as a Lecturer of Singing at the UFS, he looks forward to engaging in more performing projects with his students.

In recognition of Albertus Engelbrecht’s remarkable achievement, the UFS community congratulates him on this significant milestone. His dedication to the field of vocal studies and commitment to fostering versatility in music is truly commendable.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers.

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
