Dr Alexandra Parker

Senior Researcher

Alexandra Parker’s research explores the intersections of people, their cultures and identities, and urban and suburban environments. Her current research is diverse and examines the roles of motherhood identity, graffiti, streets as public spaces and school feeder zones in shaping the Gauteng city-region. Exploring personal identities, cultural practices and social experiences offers alternative insights into the functions and dysfunctions of city spaces. Alexandra has a growing enthusiasm in the work of visually disseminating research findings through exhibitions, data visualisations, explainer videos and exploiting social media platforms.

Alexandra Parker joined the GCRO in late 2016 after a long and fruitful association with the University of the Witwatersrand as an undergraduate and postgraduate student and as a postdoctoral research fellow. She completed her PhD in town and regional planning in 2014 (Thesis Title: Images and Influence: The Role of Film in Representing Johannesburg and Shaping Everyday Practice in the City) published as the monograph Urban Film and Everyday Practice: Bridging Divisions in Johannesburg (2016, Palgrave Macmillan). Her doctoral and postdoctoral research explored the influence of urban films on everyday practice in the cities of Johannesburg and Cape Town. Alexandra began in the field of architecture for her undergraduate and masters degrees. She has a passion for teaching and engaging with students and has taught courses in planning and architecture at the Wits School of Architecture and Planning; the Graduate School of Architecture, University of Johannesburg; and a Masters course at the Università Iuav di Venezia, Italy.

She serves on the Johannesburg Heritage Foundation board and is chair of the Joint Building Plans Committee (East) actively campaigning to protect the city’s heritage. She is a director on the board of the Architects’ Collective, promoting architecture and the built environment through cultural activities. In 2017 Alexandra was recognised as one of Mail and Guardians 200 Young South Africans.

Her research interests include: film, cinema and media; suburbia; urban studies education; culture and space; built heritage; place identity; and data visualisation.

Dr Ngaka Mosiane

Senior Researcher

My research interests centre around, provocatively, ‘the transformative potential of cities’. I use numerous entry points into this area of research. The first one is livelihoods, through which I examine how ordinary people use the city’s resources to reshape their lives within the context of changes in historical practices of livelihood formation, landscape forms and social identities. The second entry point is the state’s spatial interventions – the ways in which such interventions (the Master Plan, for example) facilitate and/or hinder ordinary people’s livelihood activities. The third vantage point into exploring the transformative potential of cities is the ways in which social payments, (local) state spending, and basic municipal services contribute to ordinary people’s livelihood assets. Taken together, I deploy these themes to reflect on the extent to which ordinary people are able to harness the city’s resources to build livelihoods and to use such livelihood assets to pursue their aspirations.

My other area of research interest is the intellectual history of informal housing: its major dimensions, the changes in the way this topic has been treated over time, the current emphases and future directions of informal housing research, theory, and methodology.

Dr Richard Ballard

Specialist Researcher

Richard Ballard trained in the field of geography, having completed an Honours Degree in Geography at the University of Natal in 1994 and a PHD in Geography at the University of Wales, Swansea, in 2002. His research has followed two broad themes.

The first is the way in which white people have experienced desegregation as experienced in post-apartheid cities. This includes reactions to street traders, shack dwellers, desegregating suburbs, and an analysis of gated communities.

The second is the way in which government and the public interact in the context of poverty and joblessness, with a particular interest in social movements, participatory mechanisms, the role of ward and PR councillors, and social policy mechanisms such as cash transfers.

His research at GCRO is on urban mixing, new large scale private developments and social cohesion.

Sandiswa Sondzaba

Research Intern

Sandiswa joined the GCRO as a research intern in 2019. She recently obtained an MSc in Human Geography from the University of the Witwatersrand. Additionally, she has a BA in Philosophy and Politics and a BA Honours in International Relations from the same institution. Her MSc research focused on how technocrats’ perceptions of Alexandra Township influenced their attempts at implementing the Alexandra Renewal Project’s aims and objectives. Her previous research focused on how legalising sex work would affect sex workers operating in different spaces across post-apartheid Johannesburg. More broadly, Sandiswa is passionate about social sciences research and understanding the implications of policies and planning on the development of equitable urban spaces across post-apartheid South Africa. As a 2015 Abe Bailey Travel Bursar and 2016 Brightest Young Minds, she is also aware of the importance of making academic insights more accessible to wider audiences in a bid to support evidence-based leadership. She has written extensively on various subjects around socio-economic and politics in contemporary and her writing has been featured in Africa Matters’ blog and The Daily Maverick.

Thembani Mkhize

Junior Researcher

+27 11 717 7698

Thembani completed his MSc in Town and Regional Planning (Urban Studies) at Wits University in 2014. His research report, titled 'Managing Urban (Neighbourhood) Change for whom? Investigating the Everyday Practices of Building Managers in eKhaya Neighbourhood CID Hillbrow South,' explored the relationship between external and internal space management in inner-city Johannesburg’s Residential City Improvement Districts (RCIDs). The research uses (the everyday governance practices of) property caretakers – in their capacity as ‘transmission belts’ between tenants and other stakeholders in the RCID (property owners, the City, CBOs, etc.) – to understand the particularities and peculiarities of this relationship. The study is particularly interested in the extent to which the eKhaya property managers - via their everyday governance practices - appropriate, bend, resist, accept and adhere to norms governing the RCID, and what this means for inner-city management. He is a member of the Golden Key International Honour Society (GKIHS) and was also a recipient of the Royal Town Planning Institute (RTPI) Planning Summer School Award.

In 2015, Mkhize was one of ten young researchers researching and writing up on innovative local and international responses to urban pressures that could be replicated in the South African context, and which will be documented in an edited book yet to be published by the DPME and the University of the Witwatersrand. He used eKhaya, in its capacity as an innovative response to urban crime and grime. Between late 2015 and early 2016, he assisted the DPME research team with the searching, collation, organisation, appraisal and coding literature on human settlements, in a project titled Evidence Mapping exercise in preparation for a Systematic Review in Human Settlements

With a research report titled The Challenges posed by the Political (Re)Branding of Competitive South African Cities: The case of (City and Street Name Changes in) Pretoria/Tshwane, Mkhize in 2012 graduated at the top of his class in the BSc(Hons) Urban and Regional Planning programme. The research report explored the extent to which branding/marketing and politics, two fundamentally different disciplines/concepts, converge and make themselves spatially manifest in the renaming of post-apartheid South Africa’s streets and big cities.
