Current Research

Current projects:

  • Survivorship and ecological impacts of the non-native invasive coqui frog (Eleutherodactylus coqui) in native Hawaiian forests
  • Density of non-native black rat (Rattus rattus) in Hawaiian forest ecosystems
  • Movement pattern and habitat use of the Yosemite toad (Anaxyrus [= Bufo] canorus) in the Sierra Nevada mountains
  • Landscape genomics of two ecologically important tree species, koa (Acacia koa) in Hawaii and valley oak (Quercus lobata) in California
New project (to be started in 2014):
  • Impact of non-native predators on pollinators and native plant reproduction in a Hawaiian dryland ecosystem

Research Interests

I am interested in the conservation of endemic wildlife species and native ecosystems in Hawaii and California, particularly in relation to environmental change such as non-native invasive species, forest management activities, and changing climate. Major objectives of my research include (1) determining ecological impacts of non-native invasive wildlife species in Hawaii, (2) investigating the ecology of native amphibian species in California, and (3) developing landscape-level studies related to the conservation and management of endemic species in both Hawaii and California.
