The main goals of my research are to better understand:

  • the ways in which the composition, physical structure, and phenology of Arctic vegetation are changing in response to climate change (Project websites: NASA: Forest-Tundra Ecotone, and, NASA: LiDAR and tundra shrubs)

  •  how these changes impact resident and migratory animals and in turn how animals mediate climate-induced change in the region (Project websites: NSF: TeamBird,  NASA: Animals on the Move, and NSF: TeamVole)

  • how near and remote-sensing techniques can be used to study dynamics in ecological form and function (see above projects)
