Research interest revolves around pharmacokinetic & pharmacodynamic modelling and translational medicine.
Current work involves the application of pharmacometrics in human and animal clinical trial of Mitragynine speciosa, stroke related studies, medication safety in paediatrics, pharmacovigilance and clinical pharmacy related studies.

Ongoing Research

1. Factors Affecting Tacrolimus Concentrations In Malaysian Adult Kidney Transplant Recipients (Malaysian Pharmaceutical Society Malaysia Grant)
2. Adherence to Stroke Guideline and the Pharmacoeconomic Outcomes
3. Modeling the Pharmacokinetics and Pharmacodynamics (PKPD) of Kratom Juice Ketum and Pain Tolerance (Centre for Drug Research USM under HiCOE grant)
4. Modeling the Mitragynine and Brain PKPD (Centre for Drug Research USM under HiCOE grant)
