We use epidemiological and evolutionary models to address questions in human vector-borne disease. Alongside this we work on the ecology of the vector mosquitoes themselves.
For example the four serotypes of dengue show a characteristic out of phase pattern in Bangkok, while the phylogenetic analysis of the data shows evidence of an immune interaction between the serotypes. We used models to show that partial cross-immunity was sufficient to cause the out of phase dynamics providing evidence for cross-immunity between dengue serotypes.

We had previously shown that the large difference between the dengue serotypes could be explained by antibody dependent enhancement on death.

Further models look at the role of the mosquito transmission in dengue and fieldwork is being carried out in Pakistan and Thailand on Dengue vectors.
We have also looked at the dynamics of Malaria in northern Thailand.

And built a dynamical seasonally forced model of the malaria that looks at reasons for the contrasting epidemic dynamics of malaria in Thailand and Kenya.

Work on mosquitoes has looked at host fidelity in Japanese encephalitis vectors and more applied entomology on Aedes.
