Research interests
I am interested in the evolutionary processes that originate “mega-diverse” biotic assemblages and the role of ecology in shaping the evolution of diversity. My lab studies the diversity, evolutionary history and conservation of fishes, particularly those from the Neotropical region of South and Central America. My research program focuses on the evolution of ecological and morphological specialization in driving phylogenetic divergence. Through fieldwork and collections studies we combine systematics, comparative morphology, and ecology, focusing on five goals: (1) describing the diversity and inferring the evolutionary relationships among genera and species of Neotropical cichlids and other fishes, (2) analyzing timing, rates and patterns of lineage and phenotypic diversification, (3) describing correlations between ecology and morphology in a phylogenetic framework, leading to development and testing of adaptive hypotheses, (4) analyzing patterns of ecological assembly to elucidate the effect of evolutionary history and adaptation on species interactions, and (5) determining the human impacts on Neotropical fishes and promoting their conservation.

Student opportunities in lab
There will be limited opportunities in the lab for highly motivated candidates, passionate about research topics on Neotropical freshwater fishes. I am especially interested in hearing from candidates with a strong affinity for one or more of the research lines in the lab. Prospective applicants should be able to demonstrate strong academic achievements, relevant previous training or research experience, and a clear passion for research and career development. Prospective students should contact me by email with a statement of interests, a CV or resumé, and unofficial transcripts.
