Areas of research interest
Vector biology
Host:pathogen evolution
Insect endosymbionts

My research group studies the genetic basis of mosquito vector:pathogen:endosymbiont interactions.  Specifically, we are interested in how genetic diversity and coevolutionary forces in these three partners affect transmission of arboviruses.  We use quantitative genetic, experimental evolution, genomic and molecular biology approaches.
