Epstein-Barr virus biology and translational research:

  • Dr Chiang's lab focuses on the understanding of host-virus interactions in Epstein-Barr virus (EBV) infection and on the elucidation of pathogenic mechanisms of EBV in lymphoid and epithelial cancers.
  • Research programs include:
    1. Role of T cell and NK cell immune responses in the control of EBV in patients with infectious mononucleosis, post-transplant lymphoproliferative disorders and EBV-associated haemophagocytic syndrome
    2. Next generation sequencing of EBV genomes in nasopharyngeal carcinoma biopsies and saliva of NPC patients and population carriers
    3. Action of histone deacetylase inhibitors and novel organic compounds in the activation of lytic cycle of EBV in cancers

Immunology:

  • Cord blood dendritic cell and T cell development; mannose-binding lectin; single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs) in immunological and infectious diseases; vaccines study disease; epidemiology of allergic diseases.
  • Immune responses to respiratory pathogens, such as human and avian flu, SARS-CoV, RSV/hMPV and mycobacteria.
  • Roles of mannose binding lectin in infection and immunity.
  • Lupus pathogenesis − how tolerance is breached.

Molecular basis of mammalian development and genetic diseases:

  • The molecular control of development and how abnormalities in this process lead to diseases.
  • Current projects on genes that affect chromatin structure and therefore the expression of other genes in neurons and neuroblastoma cells.

Human Genetics and Bioinformatics:
Molecular diagnoses of monogenic diseases; population genetics; genetic studies of complex diseases (for students with a background in medicine or biological sciences): we use cutting-edge tools in genetics and genomics to uncover genes involved in various human diseases.

Integrative genomics, systems biology and bioinformatics (for students with computation or statistics background): we focus on analyses of large amount of genetics and genomics data to gain biological insights. Please also see paed.hku.hk/genome.

Clinical genetics and genomics:

  • Medical application of whole-genome technologies: Using cutting-edge technologies including copy number variants arrays, whole exome/genome sequencing and DNA methylation array, we identify novel variants/genes involved in the pathogenesis of human diseases. Current projects include:
    • Clinical genetics and genetic counselling: Disease burden, clinical manifestations and natural history of genetic syndromes; discourse analysis in genetic counselling in different clinical settings including prenatal diagnosis, preimplantation genetic diagnosis.
    • Epigenetics: we study various common and rare disorders in which epigenetics or imprinting is implicated in the pathogenesis.
