I am an evolutionary ecologist interested in understanding the forces and mechanisms that shape an organism's evolutionary trajectory. Biotic interactions between communities, populations, and organisms are critical drivers of organismal evolution. Modern sequencing techniques have revealed that these interactions are not limited to the macroscopic world but also shape micro-organismal communities. At the confluence of the two worlds, macroscopic hosts and the microbes interact and shape each other's evolutionary trajectory. I want to trace these biotic interactions at different organizational levels in my research, starting from host communities to individual hosts, host-microbiome interaction, and microbial communities to understand their impact on organismal evolution. I use wild and laboratory-reared insect populations as the model systems for my research.
