Dr Engela van Staden
Dr Engela van Staden started as Vice-Rector: Academic on 1 January 2019.
The Executive Committee of the Council (on behalf of Council) of the University of the Free State (UFS) approved the appointment of Dr Engela van Staden as Vice-Rector: Academic during a meeting held on 5 December 2018. She started on 1 January 2019 as Vice-Rector: Academic (designate) and will take up the position from 1 February 2019 as Vice-Rector:  Academic. Prof Hendri Kroukamp, who acted in the position of Vice-Rector: Academic, will resume his portfolio as Dean: Faculty of Economic and Management Sciences on 1 February 2019. 

“Dr Van Staden has an immense knowledge of the higher-education system, governance, planning, and policy frameworks within the sector, and of enrolment planning and management, and will provide leadership within this domain. She has been in senior management positions at faculty, institutional, and national level for a period of 20 years and is one of the experts in academic-programme development and curriculum design in the country. I look forward to working with her and welcoming her to the university,” says Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.
 
Dr Van Staden holds a DPhil in Education from the Rand Afrikaans University (now University of Johannesburg). She was Deputy Vice-Chancellor: Teaching, Learning and Community Engagement at the Sefako Makgatho Health Sciences University. Prior to this she was, among others, Chief Director: University Academic Planning and Management Support at the Department of Higher Education and Training (DHET) from 2009 to 2017, Director: Strategic Management Support at Tshwane University of Technology from 2004 to 2009, Dean: Faculty of Education and Director: Strategic Planning at the then Technikon Northern Gauteng from 1996 to 2003. 
 
Her responsibilities at the Sefako Makgatho Health Sciences University included teaching and learning, quality assurance, strategic and academic planning, technology and education innovation, planning and reporting for and on earmarked and development grants, curriculum reviews, infrastructure planning, blended learning, and the redesign of the university’s business model.
 
In the portfolio of Chief Director: University Academic Planning and Management Support at the DHET, she was responsible for, among others, the national enrolment targets of 2013 and 2019, and institutional performance targets aligned to the Minister’s performance targets, the management and approval of all national programme applications, the development of the distance policy for universities / open learning strategy, the monitoring of universities under administration, the Medium Term Expenditure Framework (MTEF) budget allocations to universities, the planning and establishing of new universities in Mpumalanga and Northern Cape with specific reference to the academic programmes and governance and policy environment, and the establishment of the Central Application System (CAS) and Service and Clearing House Mechanism (CACH), which includes a project management office, business architecture and the formulation of proposals towards the governance and management of such a function.
 
She has supervised master’s and doctoral students, authored and co-authored a number of academic articles, compiled a vast array of technical reports, and participated in a wide variety of national and international projects in South Africa and abroad.

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.
