Fields of interest:
Using a unique combination of measurement techniques, my research aims at improving our understanding of the multi-trophic level consequences of climate change in the arctic tundra ecosystem. Together with colleagues both at Lamont and at other institutions, I am currently exploring: (1) The impact of climate warming and changing seasonality, on the interactions among vegetation, insects and songbird communities in an Arctic tundra ecosystem, on the North Slope of Alaska (field surveys, in situ remote sensing, bioacoustics) Project Webpage New York Times Field Blog (2) Understanding burn severity sensing in Arctic tundra: Exploring vegetation indices, sub-optimal assessment timing and the impact of increasing pixel size (field surveys, in situ and satellite remote sensing, bioacoustics) (3) Use of remote sensing to study changes in biophysical structure associated with shifts in species dominance in Arctic tundra (field surveys, in situ and airborne remote sensing)
(4) Development of a remote sensing based method for short- and longer-term forecasting of reindeer pasture and caribou seasonal rangeland quality following tundra and taiga wildfire (field surveys, in situ and satellite remote sensing)
