Dr Zama Katamzi-Joseph

Unit: Science Research and Applications Position: Researcher Qualifications: PhD

Dr Katamzi-Joseph completed her BSc in Physics at the University of Cape Town (UCT) in 2004. While at UCT she was placed on the Dean’s Merit List in 2002. In 2005 she joined the National Astrophysics and Space Programme (NASSP) for BSc Hon and MSc training. After completing her MSc with distinction at the University of Rhodes in 2007, she obtained her scholarship to do her PhD at the University of Bath in England. In 2011, she graduated with a PhD, specialising in ionospheric physics. After more than 3 years in the UK, she returned to South Africa to join the Space Science directorate of the South African National Space Agency (SANSA), where she is working as a researcher. Her main research interests include ionospheric dynamics and the influence of geomagnetic storms, thermospheric dynamics from neutral winds measurements, coupling between the thermosphere and ionosphere through traveling ionospheric disturbances and tides. She has published several academic papers and presented in numerous national and international conferences.

Dr Katamzi-Joseph is also a research associate in the Department of Physics and Electronics of the Rhodes University as well as a Royal Society – Newton Advanced Fellowship. She supervises several postgraduate (i.e MSc and PhD) students at Rhodes University. She is passionate about science advancement and actively participates in outreach projects aimed towards promoting science and technology to the youth and the general public.

Research Interests

  • Ionospheric dynamics and perturbations (i.e. traveling ionospheric disturbances, ionospheric storms, tides)
  • Thermospheric dynamics (e.g. thermospheric winds)
