I am a Postdoctoral Research Fellow in Holocene Paleoecology at the La Brea Tar Pits & Museum, part of the Natural History Museum of Los Angeles County. My work is at the intersection of ecology, paleontology, and conservation biology.

Genomes, bones, and sediments hold clues to how organisms responded to challenges in the past. I apply a diverse methodological toolkit to reconstruct the ecological histories of presently threatened species and the ecosystems in which they live, and place these results in a conservation context.

I employ toolkits that can accommodate data from fossil, historic, and modern specimens, such as stable isotopes, DNA, morphology, and species distribution models. I conduct fieldwork that includes both excavations of Pleistocene/Holocene sediments and non-invasive surveys of extant mammals. Natural history collections provide invaluable contributions to my research.

Current projects include:

  • Stable isotope analysis of California’s last grizzly bears
  • Paleoecological reconstructions of a 50,000 year old woodrat midden
  • Ecology and conservation of the Hispaniolan Solenodon
  • Extinction dynamics of Caribbean mammals
  • Developing interdisciplinary partnerships for conservation paleobiology in urban and island settings

I strive to include stakeholders, students, and conservation professionals from local communities wherever possible at all stages of my research.
