Description of Research Expertise

Research Interests
- Epidemiology of parasitic and infectious diseases
- Parasite population ecology
- Mathematical modeling of infectious and parasitic diseases of veterinary and medical importance
- Public health.

Research focus: the use of mathematical modeling techniques to facilitate the control of infectious and parasitic disease. Areas of interest include parasite population biology; the epidemiology of parasitic diseases (including those caused by viruses and bacteria); mathematical modeling of parasitic diseases of veterinary and medical importance; and economic evaluation of chemotherapeutic and vaccination strategies.
