Biography

I am a biologist investigating viruses at the interface of agricultural and natural ecosystems. My research integrates genomics, metagenomics, and computational analysis with ecological concepts to reveal the dynamics of host-virus interactions in the ecological landscape. I investigate plant, fungal, and insect vector-virus interactions, and explore how the virome shapes host communities across environmental gradients. My goal is to identify the ecological drivers of viral diversity, co-infection, and emergence to inform effective disease management strategies that support sustainable agriculture and ecosystem resilience.
