My research is focused on the origin and evolutionary history of Madagascar’s modern fauna, one of the most unique and endemic on the planet. How, when, and from where they arrived has remained largely unknown due to a 65-million-year gap in the fossil record that occurs precisely within the time period during which the modern vertebrate groups are hypothesized to have colonized the island. My research has sought to fill in this “gap” in a number of different ways. I also continue to collaborate with colleagues on projects examining dental development, life history, anatomy and growth in both living and subfossil lemurs. These collaborations have examined life history variation in extant and extinct primates (including electron microscopy and ontogenetic studies of dental eruption and root formation), and collected data from captures of wild lemurs to characterize their growth and health in pristine forest and disturbed fragments.
