My research quantifies genetic and, particularly, kin structure on the scales relevant to conspecific interactions and studies the impacts of this genetic structure on the ecology and evolution of marine organisms. I also study the links and feedbacks between processes that generate fine-scale genetic structure, namely dispersal and gene flow.  Because of their unmatched diversity of reproductive and developmental modes, I work primarily with marine invertebrates.  

We are becoming increasingly aware that fine-scale genetic structure on ecologically relevant scales, from centimeters to meters, appears to characterize many marine populations, even in species with extensive dispersal potential, and even when populations seem to be genetically homogeneous over much broader spatial scales. We also know that a growing number of studies on marine organisms shows that the density and genetic composition of groups of interacting conspecifics – the social environment – can exert strong effects on many critical aspects of performance (e.g., growth rates; biomass; disease and invasion resistance; settlement behaviors; and fertilization success), across all levels of biological organization, from individuals to ecosystems.

Specifically I am interested in (1) how social dynamics within families can play a role in the evolution and expression of life histories, behavior, and reproductive isolation; and (2) how social dynamics among members within a group can influence population productivity, persistence and ecosystem function in general.

To a lesser degree, I also explore the relevance of these ideas with respect to the reproductive biology and conservation of endangered sea turtle species.
