The central focus of my research program is to investigate evolutionary patterns and processes of biodiversity in fishes. I use phylogenetic trees as invaluable tools for understanding taxonomy and species diversity, the effects of geography and paleogeography on lineage diversity, macroevolutionary consequences of shifts between habitat types, and adaptive evolutionary change in novel anatomical systems. In the work proposed here, my research group will infer phylogenetic relationships for two groups of fishes: the drum (Sciaenidae) and the Neotropical electric knifefishes (Gymnotiformes). Phylogenetic trees for these groups will form a basis for understanding the evolution of aquatic habitat transitions, and the evolution of electricity as a sensory modality.

我的研究计划的中心重点是调查鱼类生物多样性的进化模式和过程。我使用系统发育树作为理解分类学和物种多样性的宝贵工具，地理和古地理对谱系多样性的影响，栖息地类型之间的变化的宏观进化后果，以及新的解剖系统的适应性进化变化。在这里提出的工作中，我的研究小组将推断两组鱼类的系统发育关系：鼓（石首鱼科）和新热带区电刀鱼（裸形目）。这些群体的系统发育树将为理解水生栖息地过渡的演变以及电作为一种感觉方式的演变奠定基础。
