Research Interests

  1. Dissecting the tripartite interaction between mosquitoes, their microbes and the pathogens they transmit.
  2. Identifying and characterizing the molecular mechanisms facilitating bacterial symbiont – mosquito interactions.
  3. Understanding how adaptation to the mosquito host shapes symbiont genomes.
  4. Developing new genetic tools to manipulate insect vectors.
  5. Investigating novel microbial control approaches to reduce arthropod-borne disease.
