Dr Mirriam Moleko, a lecturer in the Department of Mathematics, Natural Sciences, and Technology Education in the UFS Faculty of Education, participated in the National Research Foundation’s Black Academics Advancement Programme fellowship and got the opportunity to visit universities and schools in the USA for three weeks.

After completing the National Research Foundation’s Black Academics Advancement Programme (BAAP) fellowship, a lecturer from the University of the Free State (UFS) now wants to train more teachers on issues of access and inclusivity in different mathematics settings. She also wants to establish a centre for access and inclusivity to promote quality teaching that caters to a diverse learner population.

Dr Mirriam Moleko, a lecturer in the UFS’s Department of Mathematics, Natural Sciences, and Technology Education in the Faculty of Education, participated in the BAAP fellowship, an initiative of the National Research Foundation (NRF) and the FirstRand Foundation (FRF), from 2021 to 2022. She also got the opportunity to visit universities and schools in the USA for three weeks.

Supporting emerging academics

Dr Moleko says the BAAP is a prestigious NRF programme which supports well-structured research projects with achievable aims, sound methodologies, and demonstrated prudent use of funds. The programme supports emerging academics to ensure that they develop strong research skills, collaborate with prolific scholars in their fields, visit other universities abroad, give public lectures, and attend international conferences to establish an international footprint.

“The programme allows the candidates awarded the grant to focus on research for two years” she says. “I managed to run my teacher community research project successfully during this period. My goal as an academic and a researcher is to produce work that teachers can relate to and be able to apply in their profession. I have always aspired to empower teachers to be knowledgeable and resourceful”.

“Furthermore, my goal is to strive to partake in critical conversations that are taking place within the mathematics education field, and to contribute my skills and knowledge in addressing the existing challenges, thus being part of the solution. I believe the skills that I have gained on how to conduct quality research will assist me in achieving my goals,” she added.

Benefit from funding

During the period of her fellowship she learned about forming partnerships and collaborating with other scholars in her field, which she believes is an important skill to possess as a developing scholar.

Dr Moleko says the programme played a pivotal role in the attainment of numerous significant accomplishments in her professional career thus far. She also benefitted in terms of funding, which helped her undertake autonomous research and advanced training in her area of expertise, as well as facilitated engagement in collaborative research ventures with esteemed professionals and researchers, both domestically and abroad.

“The research leave that I got enabled me to successfully conceptualise, strategise, and implement a research endeavour that yielded a more profound comprehension of the research gap that I had identified within the teacher community, thus culminating in multiple publications in esteemed periodicals.

“The NRF-BAAP funding also enabled me to undertake training, thereby refining my skill set and augmenting my comprehension of intricate principles. The experience proved to be a crucial factor in my vocational growth and bolstered my aptitude for scholarly inquiry. It also afforded me the chance to engage in mentoring endeavours for fledgling researchers.”

Transformation of the Professoriate Mentoring Programme

Dr Moleko, who is part of the UFS Transformation of the Professoriate Mentoring Programme, says this programme is an excellent initiative which is aimed at preparing young academics for future promotions and offering them skills to be competitive. The programme’s goals include building strong academics who will follow in the footsteps of the university’s current leaders.

She says the programme is critical in supporting young academics by connecting them with seasoned mentors and scholars from various fields of study. It is essential for young academics in terms of maximising their learning, expanding their network, and gaining opportunities to help facilitate their growth.

“I see the programme as a catalyst for change necessary for the university to realise the desired results,” Dr Moleko says.

During her visit to the USA she spent two weeks at Boston College and the University of Rhode Island, and also visited the Center for Applied and Specialised Technology, the Paul V. Sherlock Center on Disabilities (Sherlock Center), and the TechACCESS Center.

“The purpose of my visit was to establish networks and collaborate with prolific scholars outside South Africa on research engagements. Furthermore, the visit was intended for me to meet with my international mentors in person regarding research engagements.

“During my research visit, Prof Elizabeth Dalton from Rhode Island University and a UDL specialist, and I focused on several academic conversations and demonstrations of Universal Design for Learning (UDL) strategies and approaches, as well as the sharing of many online resources available to support the implementation of UDL in inclusive settings.”

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.
