Research Summary:

Mosquitoes are effective disease vectors because adult females require vertebrate blood for egg development.  Research focus of my laboratory is on studying molecular mechanisms linking blood feeding with the egg maturation.  We have discovered that the evolutionary conserved signal transduction pathway - target of Rapamycin (TOR) -  is utilized by mosquitoes to indicate the presence of blood in their guts to activate egg development after a blood feeding.  The steroid hormone gene regulatory cascade represents a second pathway activated by a blood meal. Both gene regulatory pathways are being studied by RNA interference and genomics.  Through the tools of modern technology we are bringing the laboratory discoveries to explain molecularly ecological data of mosquito needs for multiple blood feedings that markedly increase spread of disease.

Another focus of my laboratory is mosquito immunity. A reverse-genetics approach utilizing a transgenic technique permits to study contribution of different organs into overall immunity. Using this approach, we have developed mosquito strains with altered tissue-specific, gain-off-function and loss-off-function major systemic immune pathways.  These strains are being applied for infection and genomics in order to elucidate how pathogens of major human diseases, transmitted by mosquitoes, interact with their mosquito hosts.
