My research aim is to uncover the evolutionary processes that have led to the present diversity in the muroid rodent clade. Twenty-eight percent of the species diversity found in the mammalian lineage are rodents, and much of this diversity is represented by muroids (Old World mice and rats, voles, gerbils, sigmodontines, etc.). We use statistical phylogenetic approaches to examine putative evolutionary processes that have led to its diversity, such as ecological opportunity and key innovations.

Research integrates fieldwork, genetics, and museum specimens to adress a wide range of questions related to the taxonomy, evolution, ecology, and conservation of mammals, particularly rodents.

Research interests concern various aspects of molecular phylogenetics.

Interested in how populations and species respond to environmental change.

Interested in the biological causes of morphological variation, both within, and among species

Interested in the fuzzy boundary between microevolution and macroevolution.

Interested in macroevolution, biogeography, morphological evolution, and phylogentetics.

Focused on the evolution of dietary adaptation in teeth of murine rodents.

Primarily studies how phylogenetic history, dispersal ecology, and population demography interact to influence species distributions and community assembly. Invasive species are a useful model system for understanding mechanisms driving community assembly, because introduction of species to a new habitat is an unintended experiment in factors limiting species distributions.

Interested in muscle enlargement in cannibalistic spadefoot toad tadpoles and understanding how the cannibals are turning on cell growth.

Interested in understanding the adaptive divergence of cranial anatomy in fishes.

Working on the phylogeny and evolution of Drosophilid flies.

Focused on the diversification of the genus Apomys that is endemic to the Philippines.
