Research Interests

I am broadly interested in the genomics and evolution of symbiotic interactions. My research focuses on understanding how population genetic parameters and co-evolutionary interactions between host and intracellular symbionts drive genomic and functional evolution of symbioses. How do high rates of mutation accumulation in endosymbionts and organelles impact host fitness? What are the mechanisms by which hosts compensate for accelerated rates of mutation accumulation? How do different evolutionary processes shape the evolutionary trajectory of symbiotic lineages?
