Dr Matteo Grilli from the International Studies Group (ISG) became the second ISG scholar in just four years to receive a coveted P-rating from the NRF.

A P-rating (Prestigious Awards) by the National Research Foundation (NRF) is the holy grail for all young researchers at all South African universities and across all disciplines. It is a valuable tool for benchmarking local researchers against the best in the world. But it is hard to come by. Only one or two researchers are normally granted this sought-after standing each year. 

Dr Matteo Grilli, a young Italian historian from the International Studies Group (ISG), says he was “pleasantly surprised” when he recently got the nod from the NRF, attributing his P-rating to the “excellent training and support” that he received from the UFS, and specifically the ISG and its head, Prof Ian Phimister.  

Unique achievement for ISG
What makes this achievement even more significant, is that the ISG produced another P-rated scholar a mere four years ago (Dr Daniel Spence in 2016).

“For Prof Phimister to produce two P-rated researchers in such a short time is really an unbelievable achievement. I am not aware of any other department at any South African university that could achieve this,” says Dr Glen Taylor, Senior Director: Research Development. 

P-rating requirements
The NRF’s P category honours young researchers (normally younger than 35 years) who have held a doctorate or equivalent qualification for less than five years. Researchers in this group are recognised by all or the vast majority of reviewers as having demonstrated the potential to become future international leaders in their field based on exceptional research performance and output from their doctoral and/or early postdoctoral research careers.

UFS becoming a mecca for African studies
Dr Grilli produced his first book, Nkrumaism and African Nationalism: Ghana's Pan-African Foreign Policy in the Age of Decolonisation around two years ago, after being accepted as a postdoc scholar by the ISG in 2015.

This unique research centre was established towards the end of 2012, with the aim of attracting and recruiting high-calibre postgraduate students and postdoctoral fellows from all over the world to the UFS. 

“Working at the ISG has undoubtedly been the best experience of my life and made me the solid scholar I am today. At the ISG, I found the best working environment you could possibly have in an academic setting, even compared to the Northern Hemisphere,” Dr Grilli says.

He believes the centre’s strength lies in the “exceptional exchange” that researchers have with their peers, allowing them to not only master their research subject but also to learn from other members’ research and methodologies.

“In my view, the ISG is concretely contributing to bringing the centre of African studies back to the African continent,” he enthuses.

Passion for Southern African politics
Dr Grilli specialises in the political history of Ghana and Southern Africa, focusing on transnational histories of African liberation movements, the history of Pan-Africanism, the Cold War and decolonisation in Africa, and the history of European migrations in sub-Saharan Africa (particularly Italian communities in Ghana and the Congo DRC). 

He is currently working on a book project about the history of Pan-Africanism, Socialism, and Nationalism in Southern Africa, particularly in Lesotho, eSwatini, and Botswana.

Asked what advice he had for young researchers, he echoes the counsel he received from Prof Phimister at the start of his tenure at the ISG: 

“Always aim high. Don’t be intimidated by the fact that there is a lot of competition in the academia, nor that you might be disadvantaged because you work in the Global South. If you work hard, your research will speak for itself and you will be able to publish solid works even in the most prestigious journals of the Northern Hemisphere.”

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass

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.
