Dr. Melanie McLaren

Dr. Melanie McLaren

Research Fellow

Melanie is a post-Doctoral researcher with an MSc in physics from the University of the Witwatersrand and a PhD in physics from the University of Stellenbosch. Her PhD focused on quantum entanglement of photons in the orbital angular momentum basis. Melanie also has experience in optical tweezing, where tightly focused laser light is used to manipulate micron-sized particles in three-dimensions.

Hend Sroor

Hend Sroor

PhD student

Hend is a PhD student with a BSc in Physics from Menofia University in Egypt. She began her career as a physics tutor at the Modern Academy for Engineering and Technology in Egypt. Hend received a postgraduate diploma in Laser Interaction with Matters from Cairo University and was then awarded a scholarship to undertake an MSc at the African Institute for Mathematical Sciences with a research project at the University of Stellenbosch. Her MSc involved measuring, analysing and simulating the true ultrafast electron bunch duration in the Ultrafast Electron Diffractometer.

Othmane Mouane

Othmane Mouane

PhD Student

Othmane is a PhD student with an MSc in physics of materials and nanostructures, and a BSc in physics from Sidi Mohamed Ben Abdellah University in Morocco. He worked on photonic crystal fibers, and optical injected ring laser cavities at the Institut non-lineaire de Nice in France. The work investigated different non-linear phenomena and observed the topological solitons (or excitable waves).

Mitchell Cox

Mitchell Cox

PhD Student

Mitchell attained his BSc(Eng) Electrical and Information degree with distinction at The University of the Witwatersrand. After a short stint in industry, he returned to Wits to do his MSc(Physics), focusing on energy efficient and cost effective high data throughput computing for the ATLAS detector at CERN through the use of ARM System on Chips found in mobile devices. Mitchell is now pursuing his PhD in optical communications and is interested in harnessing spatial modes of light to increase the data throughput of free space optical links.

Gareth Berry

Gareth Berry

MSc Student

Gareth is a Master’s student with a BScHons from the University of the Witwatersrand. His MSc focuses on quantum imaging through quantum entanglement in the hope of performing ghost imaging  in the presence of perturbations due to mode coupling in fibres or in a turbulent atmosphere.

Isaac Nape

Isaac Nape

MSc Student

Isaac obtained his BSc (Hon) in Physics at the University of Pretoria where he also did a series of projects under the SARCHI Chair in Carbon Technology. He is currently doing his MSc Physics at the University of Witwatersrand with the Structured light group where he is exploring his deep interest in Quantum entanglement. His MSc research focuses on hybrid quantum entangled states which can be used in quantum communication or computing. Hard work beats talent” Kevin Durant

BigBoy Madlala

BigBoy Madlala

MSc Student

Bigboy attained his BSc majored in Physics and Nuclear sciences and BSc(Hons) from the University of the Witwatersrand (Wits). He is currently doing his MSc at Wits, focusing on the design of a passively Q-switched Nd:YAG laser transmitter.

Lucas Gailele

Lucas Gailele

MSc Student

Lucas holds a BSc degree in Computational and Applied Mathematics and Physics, with a BSc(Hons) degree in Physics from the University of the Witwatersrand. He currently holds an MSc studentship with the CSIR. Lucas is looking at ways in which I can use the light patterns (the intensity distributing as seen in a camera) to propagate large bits of information through free-space. He will be using both radial and azimuthal degrees of freedom in the patterns and employing long range non-diffracting light beams as an information carrier to demonstrate high-bit-rate data transfer using a 2um laser source.
