Current Research

My research focuses on phenology, the study of seasonal biological events. I measure and model phenology and growth of Douglas-fir in genecology studies, and model the distribution and phenology of culturally important shrubs across the Pacific Northwest. I work with over 15 industry and government seed orchard managers to collect reproductive phenology data, and parameterize phenological models to be used to help time management activities and predict tree responses to climate change.

Research Interests

  • Utilizing information from common garden studies, citizen science observations, and long-term monitoring plots to explore how changes in temperature and precipitation affect plant phenology, growth, resource use, and competitive interactions
  • How climatic conditions, genetic adaptations, and interactions between plant species determine community responses to environmental change
  • How such alterations in plant communities affect important ecosystem services

Past Research

I collaborated with over 30 scientists and stakeholders around the world to compile large databases on Arctic and alpine plant community characteristics and environmental conditions.

Why This Research is Important

The results from my collaborative work utilize data from many different locations and over many years, and these syntheses are extremely important for accurately measuring how ecosystems are responding to environmental changes at a global scale. Information from my research can be used to predict changes in tree and shrub phenology as the climate changes, and identify promising species and genotypes for restoration and reseeding that may be resiliant to climate change.
