Overview of Laboratory

The long term primary goal of my lab is to elucidate the molecular events underlying Parkinson Disease (PD), with the view to develop novel therapies aimed at effectively treating the disease. To realise this goal progressively, our research work focuses on achieving the following inter-related objectives:

  1. MECHANISMS – To identify and characterise key players/events that contribute to PD pathogenesis
  2. MODELS – To generate reliable preclinical models of PD that would facilitate drug discovery efforts
  3. MARKERS – To generate selective biomarker probes for disease diagnosis and monitoring
  4. MEDICINE – To develop therapeutic strategies based on the knowledge gleaned from our research work

Our other interest is to explore the relatively poorly characterised but intriguing relationship between PD and cancer. This is a novel angle that we have taken, which we believe might shed important insights into the (paradoxically) shared mechanism that underlies the opposite cellular fates of the two seemingly disparate diseases. We are collaborating with A/Prof Ang Beng Ti and Dr Carol Tang from the Neuro-oncology Program to address this.
