Satellite remote sensing of landscape features that possess high-frequency dynamics, such as sea ice distribution and vegetation phenology, and spatial analyses of how wildlife migrations are influenced by habitat and weather dynamics.
My projects aim to pioneer new analytical avenues in applied wildlife research by combining remote sensing with traditional wildlife studies to answer questions about habitat use and animal movements at landscape scales. The studies I engage align with Department of Interior priorities in the Arctic by addressing a growing need to understand how changes in climate or land use practices affect wildlife migrations, habitat availability, habitat quality, and population dynamics. Climate is the overarching force that controls wildlife habitat resources in the Arctic, so understanding linkages between the physical and biological environment is critical for making informed management decisions in the face of accelerating warming and expanding human activities. My expertise includes tracking wildlife by satellite, monitoring sea ice and vegetation changes by satellite, and the implications of future climate change on Arctic wildlife in general.

Blue-winged Teal and Cross Continental Avian Influenza Transmission
This project focused on improving our understanding of the migratory ecology of Blue-winged Teal and their ability to transmit avian influenza or other pathogens across the wild bird – domestic poultry interface.
Tracking Data for Surf Scoter (Melanitta perspicillata)
Available here are tracking data of Surf Scoter, a duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. These data were collected to better understand the timing and patterns of migratory movements between breeding and wintering areas.
Tracking Data for Black Scoter (Melanitta americana)
Available here are tracking data of Black Scoter, a duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. These data were collected to better understand the timing and patterns of migratory movements between breeding and wintering areas.
Tracking Data for Pacific Loons (Gavia pacifica)
Available here are tracking data of Pacific Loons, a species that breeds throughout much of Alaska and winters throughout the Pacific Ocean basin, along the costs of East Asia and the U.S. These data were collected to better understand timing of spring arrival, fall departure, and habitat use patterns on the North Slope of Alaska.
Tracking Data for Tundra Swans (Cygnus columbianus)
Available here are tracking data of Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of habitats in breeding, wintering, and migratory areas of North America.
Tracking Data for Yellow-billed Loons (Gavia adamsii)
Available here are tracking data of Yellow-billed loons, a species that breeds in coastal areas of western and northern Alaska and adjacent regions of Russia and Canada. This species winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska
Tracking Data for Blue-winged Teal (Anas discors)
Available here are tracking data of Blue-winged Teal, a duck species that breeds throughout much of North America and whose wintering range includes neotropical areas of the Caribbean and Central and South America, thus providing a migratory link between the continents of North and South America. These data were collected to better understand the timing and patterns of migratory movement of Blue...
Tracking Data for Red-throated Loons (Gavia stellata)
Available here are tracking data of Red-throated Loons, a species that breeds in coastal areas throughout Alaska and winters along the Pacific coasts of North America and Eurasia. These data were collected to better understand the patterns of migratory movements and seasonal use of different regions of Alaska.
Tracking Data for Northern Pintails (Anas acuta)
Available here are tracking data of Northern Pintails, a duck species that, in Alaska, nests throughout the state and in adjacent regions of Russia and Canada. These data were collected to better understand the timing and patterns of migratory movements of Northern Pintails from wintering grounds in Japan as part of a project on the possible spread of Eurasian forms of avian influenza to North...
Tracking Data for Marbled Godwits (Limosa fedoa)
Available here are tracking data of Marbled Godwits, a large-bodied shorebird that, in Alaska, nests in the southwestern portion of the state. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of different coastal areas in the Pacific region.
Ecosystem Shifts in Arctic Seas
In addition to the direct effects of sea ice loss on walrus ( Odobenus rosmarus divergens) and polar bears ( Ursus maritimus) that use ice as a platform, the decline of Arctic sea ice is predicted to promote a fundamental ecosystem shift from benthic animals that forage on the sea floor to pelagic animals that forage near the sea surface.
Primary Production Sources and Bottom-up Limitations in Nearshore Ecosystems
Kelp forests are among the world’s most productive habitats, but recent evidence suggests that production is highly variable.
