Biography

Dr Chen graduated as Bachelor of Medicine with 1st class honor in 2004 and Master of Medicine (Ophthalmology) with 1st class honor in 2007 at the Shantou University Medical College. He completed his Ph.D. program of Ophthalmology & Visual Sciences at the Chinese University of Hong Kong (CUHK) in 2010, followed by 1 year post-doctoral research in CUHK, during which he won the 7th Action for Vision Young Researcher Award 2010. In November 2011, Dr Chen was appointed Assistant Professor at the Department of Ophthalmology & Visual Sciences of CUHK . He is honorary resident of the Prince of Wales Hospital and Hong Kong Eye Hospital. He is also honorary Associate Professor of the Shantou University Medical College.

Dr Chen is Editorial Board Member of the journal Scientific Reports (impact factor 5.2), and is reviewer for more than 10 international journals, including BMC Med Genet, Eye, Invest Ophthalmol Vis Sci., Medicine, Mol Vis., Ophthalmology, PLoS One, Retina, and Sci Rep. Besides, Dr Chen has delivered more than 30 lectures as invited speaker and chaired more than 10 sections in international conferences. He has published more than 75 papers in SCI international indexed peer-reviewed journals.

Dr Chen is now the Head of Graduate Division at the Department and appointed as Associate Professor in November 2017.

Results of Note 

  1. Dr Chen and the genetic team have worked on the identification of new genes and variants for major eye diseases. In the past year, the team had discovered the PGF, ANGPT2 and ABCG1 genes as new disease genes for age-related macular degeneration and polypoidal choroidal vasculopathy; identified novel associated variants in the ABCC5 gene for primary-angle closure glaucoma, and in the SIX6 gene for primary open-angle glaucoma
  2. Dr Chen is the Principal Investigator (PI) of 5 external competitive research grants, including 1 General Research Fund (GRF) from the Research Grants Council, Hong Kong; 1 Youth Fund of the National Natural Science Foundation of China (NSFC); 2 Health and Medical Research Fund (HMRF) from Food and Health Bureau, Hong Kong; and 1 Research Award from the Global Ophthalmology Awards Program (GOAP) from Bayer, Germany. The total amount of the research funds is over HK$ 4 million
  3. Dr Chen has published 85 papers in SCI international indexed peer-reviewed journals, mainly including 1 in Lancet Oncology (Impact Factor (IF): 33.9), 6 in Nature Genetics (IF: 27.959), 3 in Nature Communications (IF: 12.124), 6 in Ophthalmology (8.2), 4 in Human Molecular Genetics (5.34), 13 in Scientific Reports (IF: 4.259), and 13 in Invest Ophthalmol Vis Sci (IF: 3.303)
  4. The H-Index of Dr Chen is 19 as of August 2017
