I have background on public health medicine, health statistics, and health services research; have been conducting systematic reviews and modelling for health technology assessment, and research synthesis related methods. My research interest also includes primary research on health care interventions and health services research. 

Key research interests

  • Evidence-based medicine research; systematic reviews, meta-analysis and modelling for evaluating a wide range of health care interventions.
  • Methodological research concerning evidence-based medicine and evidence synthesis, including  publication and related biases, assessment of non-randomised studies, indirect treatment comparison, network meta-analysis, and evaluation of complex healthcare interventions.
  • Primary research on public health interventions, health services research, the control of chronic conditions, disability and rehabilitation, smoking cessation and tobacco control.
