Research Program

How we define and characterize species is a fundamental question that lies at the core of most biological disciplines and strongly influences how we formulate conservation strategies.  Despite the relative significance of understanding the very essence of one of the most basic units of biological diversity, the meaning of the term species and the process of speciation remain one of the more contentious and perhaps poorly understood subjects of evolutionary biology.  Because speciation is a multifarious process my research crosses multiple hierarchical levels of biological organization relying heavily on phylogenetic approaches that utilizes molecular, ecological, discrete morphological, and quantitative morphometric data.  The study of such a complex process requires a multifaceted approach; numerous biotic and abiotic factors like ecology, physiology, behavior, population structure, biogeography and geology influence speciation pattern and process.  

In my opinion a comprehensive research program that addresses questions related to arthropod evolutionary diversification and biodiversity requires at the very least a two-tiered approach.  In general terms we are interested in both the empirical and ontological nature of species.  First, how do we define species meaningfully for a broader audience's use in evaluating and defining Evolutionarily Significant Units for conservation purposes? Second, what fundamental evolutionary processes underlie speciation events?  In particular what roles do population subdivision and sexual selection play?  We achieve these objectives through alpha-taxonomic, phylogeographic, evolutionary, and spatial distributional studies of spider and millipede populations and species.
