Dr Fekade Sime

Laboratory Manager, Post-Doctoral Fellow

Dr. Fekade Sime is a UQ Research-Teaching Fellow and Lab Manager of the Centre for Translational Anti-infective Pharmacodynamics (CTAP). Dr. Sime acquired Bachelor of Pharmacy Degree and MSc degree in Pharmacology from Addis Ababa University, Ethiopia before joining the University of South Australia for PhD study in Pharmacy which he completed in 2015.  Dr. Sime worked as a lecturer of Pharmacology and Pharmacotherapeutics at Addis Ababa University where he also assumed senior academic positions including role as Assistant Dean of the School of Pharmacy and Head of the Department of Pharmacology and Therapeutics. After completing his PhD at the University of South Australia, he has worked as a research officer for the Burns, Trauma and Critical Care Research Centre, School of Medicine UQ.  In January 2016, he was granted UQ Fellowship for a research project on “A translational approach to optimisation of antimicrobial therapy for critically ill patients that prevents the emergence of 'superbugs'”.
Dr. Sime’s research expertise and interest include pharmacokinetics and pharmacodynamics of antibiotics, in vitro infection models, pharmacometrics, ex vivo and clinical evaluation of antibiotic dosing during extracorporeal therapies.

Dr MO. Cotta

Post-Doctoral Fellow

Having completed his PhD in March 2016 in antimicrobial stewardship, Dr Cotta has recently commenced a post doctorate funded through a competitive fellowship granted to him by the University of Queensland (2017-19). His work will seek to optimise dosing of commonly used β-lactam antibiotics in critically ill patients to maximise therapeutic efficacy and improve patient outcomes. As part of this fellowship, Dr Cotta will seek to gain necessary skills and expertise in developing study protocols for clinical PK investigations as well as conducting population PK/PD modelling and analysis. Dr Cotta is currently Deputy Chair of the Executive Committee of the Critical Care Community of Specialty Practice (COSP) for the Society of Hospital Pharmacists of Australia (SHPA) and currently supervises 3 PhD students and 3 MPhil students.

Saiyuri Naicker

Research Assistant

Saiyuri Naicker is research assistant within the CTAP PC2 laboratory. She completed her Bachelor’s degree in Applied Science majoring in Microbiology at QUT in 2011 and subsequently did an honours research year at the University of Sunshine Coast, under the supervision of A/Prof Mohammad Katouli. Her honours research thesis focussed on the dissemination of multidrug resistant bacterial strains, from the sunshine coast hospital wastewater system, into the environment post-waste water treatment and resulted in changes in the wastewater treatment guidelines by Sunshine Coast local council. She completed a Master’s in Molecular Biology degree by coursework in the School of Chemistry and Molecular Biology at the University of Queensland. Her Master’s research project was within the BTCCRC, under the supervision of Prof. Jeff Lipman and Dr Steven Wallis. The project was looking at a pharmacokinetic analysis of the stability of antibiotics in peritoneal dialysis fluid, in order to assess a method for “at home” treatment of peritonitis with antibiotics already in dialysis fluid solution. Thanks to Baxter pharmaceuticals and the Renal department at Royal Brisbane and Women’s Hospital, led by Dr Dwaraka Ranganathan, the work was published in the Peritoneal Dialysis International (PDI) medical journal. She has previous worked as a research assistant at USC within the Katouli Lab and within the BTCCRC Bioanalytical laboratory.

Our students


Aaron Heffernan

Aaron is a MD/PhD student from Griffith University who joined the Centre for Translational Anti-infective pharmacodynamics laboratory at The University of Queensland in early 2017. He has previously completed a Bachelors degree in pharmacy with first class Honours at the University of Queensland as well as a Graduate certificate in Pharmacy Practice at Monash University.
Following the completion of his Bachelor of Pharmacy in 2012, Aaron worked as a pharmacist at the Queen Elizabeth II Jubilee Hospital in Brisbane, starting his interest in the effect that antibiotic dosing has on the emergence of resistant organisms. His research involves the dose optimisation of intravenous and nebulised amikacin and fosfomycin in the treatment of multi-drug resistant Gram-negative ventilator-associated pneumonia.

Chandra Sumi

Chandra graduated in December 2012 from Stamford University Bangladesh with a Bachelors degree of Pharmacy with Honours. She then completed a Masters of Science in Systems Biotechnology at Chung-Ang University, Anseong, South Korea. During her masters she was involved in four research projects in the areas of microbiology as well as molecular biology related to a novel peptide isolated from Bacillus subtilis SC-8 as well as bacteria present in soybean paste. During her honours at Stamford University Bangladesh, she was involved three research projects related to antinociceptive activity of Cyperus rotundus, Barringtonia acutangula and Citrus grandis. Chandra has one publication as first author and two others as second author resulting from her honours and masters research work. Chandra has held an Academic Scholarship from Stamford University Bangladesh as well as the Chung-Ang Young Scientist Scholarship. Professionally she is a member of the Stamford Pharmacy Alumni Association (SPAA, Bangladesh), Bangladesh Pharmaceutical Society (BPS) and the Pharmacist Graduate Association (PGA). She is currently undertaking her PhD within the CTAP laboratory under the supervision of Dr Fekade Sime and Professor Jason Roberts.


Khor Kar Yee

"I am a 4th year pharmacy student from the University of Queensland. The emergence of antibiotic resistance raises my concern. Despite the emergence of antibiotic resistance, most of the conventional antibiotic regimens are not suitable for those cases with antibiotic resistance. By choosing Major in Clinical and Experimental Therapeutics in my fourth year, I have the opportunity to join the research team that involve in developing the optimum dosing regimen for resistant disease. We will use the hollow fibre infection model to assess the conventional dosing regimen and describe a new dosing regimen that can be used in the cases with antibiotic resistance."

Lee Fang yi

My name is Fang Yi. I am a 4th-year pharmacy student in UQ. I am an outgoing and proactive person. I have always enjoyed participating in either academic or social activities. I enjoy singing and cooking during my free time, which help me to cope with stress. Being a part of the team of a research project is challenging and enriching. Seeing how the whole team pulls together to achieve great outcomes also reinforced in me the desire to engage in research and development. Fortunately, I have an opportunity to embark on a research project. My project theme is optimisation of antibiotic therapy for antibiotic resistance by using the hollow fiber infection model. We can optimise the dosing schedule or figure out some possible drugs combination therapies through PK/PD studies to combat antibiotic resistance. Antibiotic resistance is emerging and threating human health.  I hope that I can be actively involved and able to contribute in this field in the future.
