Dianna A. Gielstra, Ph.D.


  • Ph.D., Geography
  • M.S., Environmental Studies
  • B.S., Biology

Dr. Gielstra’s past research focused on monitoring pollution remediation efforts of McMurdo Station, Antarctica, climate change studies in the subalpine treeline ecotone, and spatial pattern of tree invasion in the subalpine zone to understand competition and facilitation processes that impact landscape structure and function in Glacier National Park. Her current research interest is expanding growing gardens in schools where food insecurity is a risk and determining their use in improving school health initiatives.
