Andrew Forbes
Distinguished Professor

Andrew has at various times found himself as teacher, janitor, secretary, receptionist, web-master, systems engineer, sales rep, manager, director, and sometimes a scientist.  He is presently a Distinguished Professor within the School of Physics at the U. Witwatersrand (South Africa) where in 2015 he established a new laboratory for Structured Light. Andrew is a founding member of the Photonics Initiative of South Africa and South Africa’s Quantum Roadmap.  He is a Fellow of SPIE, the OSA, the SAIP, and an elected member of the Academy of Science of South Africa.  He holds an A-rating by the South African NRF, 3 honorary professorships, is editor-in-chief of the IoP’s Journal of Optics and sits on the editorial board of three other international journals. Andrew has won several awards, including the NSTF national award for his contributions to photonics in South Africa, the Georg Forster prize from the Alexander von Humboldt Foundation for outstanding contributions to photonics, and the SAIP Gold Medal, the highest award for physics in South Africa, making him the youngest winner to date.  Andrew spends his time having fun with the taxpayers’ money, exploring structured light in lasers as well as classical and quantum optics. 

Senior Lecturer

After receiving her MSc. from the University of KwaZulu-Natal, Angela joined the CSIR’s National Laser Centre on a PhD studentship in 2008. Her Ph.D. research involved measurement techniques for optical beams carrying orbital angular momentum. She received her Ph.D. in 2012 and subsequently commenced a Postdoctoral Fellowship followed by a Senior Researcher position at the CSIR. After 10 years at the CSIR, Angela joined the University of the Witwatersrand where she is currently a Senior Lecturer. Angela holds the SAIP Silver Medal for outstanding young physicists, and chairs the SPIE conference on Laser Beam Shaping. Her research interests lie in ‘shaping’ laser beams into various ‘patterns’ for applications with high-power laser sources.

Isaac Nape
Lecturer

Dr. Isaac Nape, a researcher in photonics and quantum computing. He specialises in higher-dimensional quantum information processing with structured light and delves into quantum search and optimization algorithms for solving complex physics problems. Dr. Nape is the Optica-WITS Emerging Leader Chair, leading efforts in quantum information processing. Awarded the Jubilee Silver Medal by the South African Institute of Physics (2023), named in Mail&Guardian’s top 200 young South Africans in technology and innovation and was awarded the Meiring Naudier Medal by the Royal Society of South Africa (2024), recognising him as an outstanding emerging scientist in his field. He also serves as the Wits-IBM liaison under the office of the DVC of Research and is tasked with driving quantum computing initiatives at Wits.

Paola Obando
Post-Doctoral Research Fellow

Paola completed her undergraduate studies in physics at the Universidad de Nariño in Colombia.  Afterwards, she moved to Argentina where she obtained a master’s degree in physics at Balseiro institute. To continue her education focused on quantum information and quantum open systems,  she moved to Brazil where she obtained her Ph.D. at the Federal Fluminense University (UFF).  Subsequently,  she commenced a Postdoctoral Fellowship at the Brazilian Centre for Research in Physics (CBPF) before becoming a postdoctoral fellow at the University of the Witwatersrand in South Africa, where she works in the Structured Light Laboratory. Her current research is related to structured light at the quantum regime, exploring its applications in quantum photonics, computation and communication.

Bertus Jordaan
Button Optics R&D Scientist

Bertus, who was born and raised in South Africa, got the chance to pursue his PhD in Quantum Information Technology and AMO physics at Stony Brook University in New York State, thanks to Fulbright and NRF scholarships. After completing his PhD, he spent a year as a postdoc at ETH Zurich before returning to South Africa, where he worked in both the private and public sectors. When he was offered a position at Button Optics, he eagerly accepted the opportunity to contribute to the company's goal of becoming internationally competitive while also promoting the growth of the photonics industry in South Africa.

Chané Moodley
Post-Doctoral Research Fellow

A physicist and physiologist with research and computational experience that spans multiple disciplines. She has worked at several research facilities, both in South Africa and Germany, conducting experimental and computational research with a strong focus on fundamental areas within physics, physiology and artificial intelligence (AI). Chané has also spent several years at a Fortune 500 company researching AI, user interface (UI), user experience (UX) and design. She has subsequently led tasks on mainstream AI research projects. Consisting of, but not limited to, applying AI to education and health care by utilising data science and machine intelligence to solve scientific challenges affecting low resourced settings in Africa. She holds specialist certificates in Machine Learning (Stanford Online) and Deep Learning. Both her academic and industrial research has led to multiple published papers, conference outputs and patents in several disciplines.

Moslem Mahdavifar
Post-Doctoral Research Fellow

Moslem completed his M.Sc. at Amirkabir University of Technology (Tehran Polytechnic), focusing on theoretical aspects of physics. During his PhD at the University of Miami, which he completed in 2023, he shifted his focus to experimental quantum optics. His doctoral research investigated the quantum nature of quasi-classical states generated from a continuous wave source. As a postdoc, he contributed to the Micro Pore Optics (MPO) project with the Astrophysics group led by Dr. Massimiliano Galeazzi at the University of Miami for a semester. Currently, he works as a postdoctoral research fellow in the Structured Light Lab at the University of Witwatersrand.

Darryl Naidoo 
Honorary Academic

Darryl Naidoo conducted his PhD research at the CSIR National Laser Centre based in Pretoria, South Africa. He received his PhD in March 2015 from Stellenbosch University and has subsequently taken up his current position as Senior Researcher at the CSIR National Laser Centre. His work is centred on laser beam shaping both extra and intra-cavity, mode measurement and laser resonators where his current research is geared towards high power beam shaping for use in laser enabled manufacturing processes. Darryl has been awarded one SPIE scholarship, 4 National Laser Centre awards and has received 2 CSIR Excellence Awards for ‘Best Student’ in 2012 and ‘Outstanding Contribution by a Team’ in 2014.
