Dr Mårten Brelén is an Assistant Professor at CUHK. He obtained his preclinical medical degree (MA) from Cambridge University where he graduated with 1st Class Honours. His clinical medical degree (BMBCh) was obtained from Oxford University and he has also spent 4 years in research at the University of Louvain in Belgium which led to the degree of PhD in Biomedical Sciences. Clinically Dr Brelén is fellowship trained at the Bristol Eye Hospital, UK in vitreo-retinal surgery and he is a fellow of the Royal College of Ophthalmologists UK (London).
Dr Brelén is the Head of retina service at the Chinese University of Hong Kong Eye Centre and is the Team Head for the vitreoretinal service at Prince of Wales Hospital. He is the Lead Coordinator of the clinical fellowship programme for vitreoretinal training and the Director of the Pao So Kok Macular Disease Treatment and Research Centre. He is also a visiting Professor at the Joint Shantou International Eye Centre in Shantou, China.
