Karthikeyan Chandrasegaran studies how mosquitoes develop and transmit disease. His research shows that early-life environmental conditions, like competition, can shape adult behaviors such as host-seeking. He uses gene expression analysis to understand how networks of genes interact over time rather than acting independently. His work also examines how environmental cues and internal biological rhythms influence mosquito traits. Overall, his research aims to improve strategies for controlling mosquito-borne diseases.
