The world’s forests are at a critical moment, where climate change and societies need for ecosystem services (i.e. wood products, carbon sequestration, etc.) are increasing both the stressors on forests, and the value of these ecosystems. My research is broadly focused on conducting applied research to develop forest inventory and monitoring methods, assist forest management decision-making, and inform broader forest policy. Within this broader objective, I use field measurements, tree-rings, and remotely sensed imagery across five major research themes:

  • Integrating field and remotely sensed data to generate spatial predictions of forest composition, structure, and change.
  • Ecology and management of Sierra Nevada mixed-conifer forests with emphasis on responses to climate change, alterations of natural disturbance regimes, and ecosystem restoration
  • Subalpine forest-meadow ecotone responses to climate change
  • Responses of tall old trees to long-term climate change and short-term drought events
  • The role of complex terrain and diverse ecosystem configurations in mediating resilience of forests to disturbance agents and climate stressors.
