Research interests:

        how microbial endosymbiont adaptation affects the niche of their hosts

        how the outcome of endosymbiotic interactions vary with environments

        how partner choice mechanisms may yield high fitness for hosts across environments

Iím researching a natural plant-rhizobia symbiosis to measure the relative importance of plant genotype vs. rhizobial genotype in persistence across serpentine and non-serpentine soils, and the influence of partner choice on the outcome of the symbiosis. Iím also researching whether spatial patterns of historical migration predict the scale of adaptation to soil chemistry and the co-adaptation between the plant and rhizobia. My research mainly involves field collections, greenhouse experiments and molecular genetics.
