    Research Interests:
    My research focuses on improving our understanding of marine decapod biodiversity by assessing species, molecular and morphological diversity, elucidating their taxonomy, estimating their evolutionary relationships (systematics), reviewing their classification, and evaluating the role of morphological characters in its evolutionary history. At my current position I will use the hermit and king crabs as a model system to study the acquisition of the crab-like form (carcinization) in the infraorden Anomura, which remains one of the greatest challenges in crustacean systematics. During the last two decades, this phenomenon has received considerable attention from evolutionary biologists and the relatively easy access to sequence data has resulted in a resurgence of interest on this topic. Unfortunately, most studies have either been based on incomplete and often inadequate data, and consequently the evolutionary pathway and concomitant morphological changes associated with carcinization remain poorly understood. Thus, I will be assembling a comprehensive morphological and molecular phylogeny and using this as an evolutionary framework for testing previous hypothesis about carcinization and identifying the most plausible morphological transitions.
