I am interested in how natural selection acts to promote cohesion or conflict between interacting genetic units, thereby facilitating or impeding the emergence of organizational complexity. Interactions can occur at numerous levels of biological organization, including between genes in a single genome (epistasis), between genes in different individuals (sociality) or between genes in different species (coevolution). Cohesion leads to co-adapted gene complexes, societies and mutualisms, respectively, while conflict leads to selfish genetic elements, cheating and parasitism. My thesis work has focused on how ecological factors (competition, resource abundance, environmental heterogeneity) and genetic factors (mutation, population structure, co-transmission) affect the rate and direction of selection on genetic interactions. In all cases, I aim to determine the signature that these forces leave on gene sequence variation, making the theory amenable to testing using the tools of molecular population genetics. My approach combines theory, simulations, bioinformatics and laboratory experiments. My empirical work has focused on microbes, particularly the social bacterium Myxococcus xanthus, while my theoretical work covers a broad (and constantly expanding) range of topics.
