Research Questions

  • How does bone and joint remodelling associated with degeneration develop and can this be controlled to reduce disability?
  • Can biomaterials remodel tissue and organs regeneration in humans?
  • How can AI-integrated modelling improve the diagnosis and treatment?

“Patience and perseverance goes a long way on your research journey” 

After beginning her research postgraduate career here at HKUMed, Yu-Ching Hsu (Year 3 PhD student in Department of Orthopedics and Traumatology) quickly found herself surrounded by a group of self-driven colleagues who served to be a great source of motivation, but also pressure to perform well, “The research culture here is that everybody is working so hard! The stress sometimes can be a little overwhelming”.

With her research centred on understanding the etiology and pathogenesis of human intervertebral disc degeneration, a typical day in the lab can entail a variety of tasks i.e. refreshing cell culture medium, cell compression, other molecular research steps such as RNA extraction and real-time PCR. Though lab work can be, in her own words, “not always joyful”, Yu-Ching also advises any future prospective researchers to trust the process. 

“Sometimes you may feel bored or even frustrated with failure, but it doesn't mean you are wrong. Just be patient, let all the negative feelings go - keep on trying – until you finally reach your goal."
