Research Interests

Amphibian decline; genetics; herpetology; conservation biology, road ecology, primate behavior

My laboratory integrates both field and laboratory work to address regional and international conservation issues. We employ genetic techniques, demographic, toxicological, and behavioral studies to address ecological and conservation questions.

  • Disease and pollutant interactions in amphibians
  • Long-term population dynamics of Chinese hynobids and ranids in the Yellow Mountains of China
  • Road ecology of Snoqualmie Pass amphibians
  • Primate behavior, social interactions, and population viability: including Tibetan macaques and Orangutans
  • Biodiversity, phylogeography, population dynamics of Kalimantan (Indonesia) amphibians and reptiles
