Josephine Reyes
Postdoctoral Fellow

Dr Josephine Reyes is a Postdoctoral Research Fellow with the Infection Analytics Program (IAP) at the Kirby Institute. Her main interests include infectious disease modelling, health economics, mathematical education and mathematical optimisation.

She also worked at the School of Public Health and Community Medicine UNSW on economic evaluation and epidemiological impact of vaccination programs. At the Kirby Institute, she also studied the cost-effectiveness of HIV/AIDS prevention programs, while also looking at the effect of adherence behaviours and treatment outcomes on the prevalence of drug resistance in HIV transmission. She obtained her PhD studying the evolution of genetic markers of tuberculosis at the School of Biotechnology and Biomolecular Sciences at the UNSW. Josephine is a trained mathematician with a bachelors and masters degree in mathematics from the University of the Philippines in Diliman (UPD). She also served as an instructor of mathematics at the UPD and as an assistant professorial lecturer at the De La Salle University in the Philippines.

Research Interests:
Mathematical modelling of infectious disease is of general interest. Other interests include the evaluation of health programs using techniques in mathematical modelling coupled with health economics to predict the epidemiological and economic impact of introducing these health programs. Past work also involves theoretical studies on the evolution of genetic markers of tuberculosis, specifically modeling the changes in the direct repeat locus as well as variable numbers of tandem repeat loci in the tuberculosis genome.

Broad Research Areas:
Disease Modelling, Mathematical Modelling, Health Economics, Epidemiology

Specific Research Keywords:
Mathematical modelling, Health economics, Infectious diseases, Tuberculosis, HIV, PCV, Rotavirus

My Research Activities

Her current work with the IAP is on modelling the dynamics of HIV, specifically on using mathematical and statistical techniques to estimate parameters related to disease progression and HIV latency. She is also working on a method to perform economic evaluation of childhood rotavirus vaccination in various settings.
