    Pharmacokinetic/pharmacodynamic modelling and simulation of ampicillin/sulbactam among hospitalized patients to determine the personalized optimal dosing against Acinetobacter baumanii infection - 2 years

Siti Maisharah Sheikh Ghadzi, Dr

Dr. Siti Maisharah Sheikh Ghadzi is a Pharmacy Lecturer in the Discipline of Clinical Pharmacy, School of Pharmaceutical Sciences, Universiti Sains Malaysia. She completed her PhD from Pharmacometrics Research Group, Department of Pharmaceutical Biosciences, Uppsala University in 2017. Dr Siti’s previous works were on the diabetes disease progression and drug effect modelling among pre-diabetic subjects, pharmacokinetics/pharmacodynamics and simulation studies related to the designs of anti-diabetes drug development as well as diabetes disease progression modelling among pre-diabetic subjects. Her current work involves the application of pharmacometrics in the clinical settings related to pharmacokinetics/pharmacodynamic modelling of several drugs as well as time-to-event modelling, and disease progression in various diseases. She is also active in clinical pharmacy-based research. Dr Siti is supervising a number of PhD, MSc, MPharm (Clinical Pharmacy) and final year projects students with several of them have been successfully passed the viva and graduated. She has been invited as a speaker and tutor for pharmacometrics seminars, nationally and internationally. Siti is also the President of the Population Approach Group of Malaysia (PAGMAS), a society (focusing on pharmacometrics research) since February 2021, after serving as the secretary from February 2018 to January 2021.
