Dr Gigi Lo obtained her BSc degree in chemistry with first class honours and PhD degree from The Chinese University of Hong Kong (CUHK). She then went to the Division of Biophysics and Bioimaging of the Ontario Cancer Institute serving as a Postdoctoral Fellow for 2 years, where she developed her research interest in “smart” theranostic agents for cancer diagnosis and treatment. Before joining the City University of Hong Kong in 2015, she was appointed as a Research Assistant Professor in the Department of Chemistry of CUHK. She has published more than 70 papers in international peer-reviewed journals.

Research Interests

  1. Exploration of smart photosensitizers for targeted photodynamic therapy (PDT) and antimicrobial PDT
  2. Development of peptide-conjugated theranostic agents for in vivo cancer imaging and treatment
  3. Engineering mesoporous silica nanoparticles and polymeric micelles for multimodal cancer therapy
  4. Development of boron dipyrromethene based quenchers as key components of smart fluorescent probes for bioimaging
  5. Exploration of nanodrugs through self-assembly of molecular therapeutic agents for cancer therapy
