Research involves understanding the basis of pathogenesis in important vectors of India and devising transmission-blocking approaches to control vector borne diseases. Our group have two major focus research areas, namely virus evolution and host/vector-pathogen interactions.
Preliminary work on studying evolution of chikungunya virus in our country revealed the emergence of a new molecular signature in Indian isolates. Work is underway to study the effect of these mutations on pathogenicity of the virus and its virulence. Using high-throughput Next Generation Sequencing platforms and computational biology approaches, my lab is involved in understanding the impact of pathogen development on insect miRNome, insect immunity and redox cascade. Our work on insect small RNA population has provided important insights to the role of microRNAs in pathogenesis and insect immunity. We are currently working on deciphering the role of viral RNAi suppressors and insect defense and the impact of co-infection of chikungunya with dengue viruses in both vector and host.
