post-doctoral research consultant, PRICELESS-SA, School of Public Health, University of the Witwatersrand

I graduated with a BSc Occupational Therapy from the University of the Witwatersrand in 1986. In 1990 I obtained an MA from the Boston School of Occupational Therapy at Tufts University (Massachusetts), funded by a Fulbright Fellowship. Having worked as an occupational therapist in South Africa, the USA and New Zealand for over 30 years - with numerous road crash survivors amongst my caseload - I then embarked on PhD research into the bioethics of road safety in the Johannesburg minibus taxi industry. I graduated in 2019 and in mid-2020 took up a post-doctoral research consultant role within Priceless (Priority Cost Effective Lessons for Systems Strengthening) in the Wits School of Public Health. I am part of the international Global Diet and Activity Research (GDAR) network, having contributed to a systematic review of travel behaviour in Africa and the Caribbean and having led on a review of active travel and paratransit (informal public transport) in African cities. My other research focus is road safety and road ethics, couched within the Vision Zero philosophy and drawing on Safe System theory. Alongside this work I continue to have a small occupational therapy practice, mostly focused on medicolegal services. I am also the founder of nonprofit company the Road Ethics Project, which offers the Thami Radebe Road Heroes Award to recognize individuals who effectively address Africa's pandemic road crashes, injuries, deaths and disabilities.
