Dr Lim is a biochemist with a profound interest in tryptophan metabolomics of human pathology. This metabolic pathway is interesting because changes to this pathway in response to environmental stimuli such as pathogens or toxins can affect five important biological functions: sleep, mood/behavioural, protein synthesis, immune response and brain activity. His research combines functional metabolomics using mass spectrometry with molecular cell biology to understand how changes in the tryptophan metabolism may affect the outlined five important functions in our body during disease condition. Dr Lim’s work is highly translational with implication for biomarker discovery and biomarker-based precision medicine.

Qualifications:

BSc (Hon I), PhD

Research Interests

  • Targeted tryptophan metabolomics as prognostic biomarker and precision medicine in human pathology
  • Role of hormones on tryptophan metabolism during inflammation
  • Screening of Chinese Medicines for novel modulators of the tryptophan metabolism
