Research Interests

  • Mathematical modeling
  • Infectious diseases
  • Developing and applying statistical methods for parameter inference for disease models
  • Pathogen predators and their use in the environment and in treatment
  • Developing intervention and vaccination policies to curtail and mitigate infectious diseases

I am interested in the interactions between environmental factors and the spread of infectious diseases. I use a combination of mathematical modelling and data analysis to understand how different environmental factors - such as climate, demography and habitat - affect the spatio-temporal spread of infectious diseases. I have been studying diseases which are directly transmitted (influenza, pneumonia), childhood infections (measles, mumps), vector-borne (leishmaniasis, malaria), sexual transmission (HPV) and enteric diseases (polio, shigella). I also combine laboratory experiments and statistical models to better estimate parameters for the use of mathematical models. An important goal of my research is to translate the academic findings and knowledge into policy setting, and improve decision-making processes.
