photo-2Yingwen was born in Beijing China and immigrated to South Africa at the young age of 8. He completed his undergraduate and postgraduate studies at the Univerity of Cape Town in South Africa. For his undergraduate studies (2004-2007) he specialized in Physics and Applied Mathematics and for Masters and Ph.D. (2008-2013) in Theoretical High Energy Physics. His Masters and Ph.D. research was completed under Prof. Dominguez and was on theoretically investigating the behaviour of quarks and mesons at deconfinement temperature. After deciding to work on something more practical for his postdoc, he moved to the Council of Scientific and Industrial Research in South Africa and worked as an experimentalist on Quantum Optics and Quantum Communications with Prof. Forbes and Dr. Roux (2013-2016). He is currently continuing his research work at the quantum photonics group with Prof. Karimi. His research interest is in using the orbital angular momentum of photons to encode information for realising high-dimensional quantum communication and computing.
