Research Interests

Paleoecology, Paleoclimate, Paleolimnology, Arctic Regions

I am a paleoecologist specializing in both climate and environmental reconstructions in the Arctic. Specifically, I examine geologic and biological material from lake sediment cores, which can provide records spanning thousands of years. Sediment cores extracted from lakes contain abundant information about how terrestrial and aquatic systems have changed through time, in response to both natural variability and recent human influences. My research combines ecological analyses of fossil material, such as insect remains and charcoal particles, with sedimentological and geochemical techniques such as x-ray fluorescence, grain size analysis, biogenic silica, and stable isotopes to reconstruct past environments. I am particularly interested how disturbances such fire and permafrost thaw have changed in tundra and boreal landscapes over the Holocene, and what this may mean for the future.

Active Research Projects

1. Navigating Disturbance Regimes in the New Arctic, National Science Foundation Environmental Engineering Grant #NSF-1927772, 2020-2025: This project is a collaboration with Dr. Mark Lara at the University of Illinois. We combine historical satellite imagery, chronosequence surveys of soils, and paleoecological reconstructions from lake sediments to investigate the relationships between fire, climate, permafrost erosion, and vegetation change on annual to centennial timescales in Arctic tundra regions of Alaska.
2. The Past, Present, and Future of Boreal Fire Feedbacks, National Science Foundation Arctic Natural Sciences Grant #NSF- 2215120, 2023-2026: This project is a collaboration with Dr. Philip Higuera at the University of Montana. We examine existing and new lake-sediment archives of boreal fires to determine how recent unprecedented fires in the Alaskan boreal forest are impacting vegetation structure, nutrient cycling, and landscape dynamics to understand how these flammable systems will respond in the future.
3. Investigate History of Vegetation and Fire Regime in Denali to Inform Fire Management Planning, US Department of Interior and National Park Service, Grant # P25AC01042-00, 2025-2030: This project is a collaboration with ecologists and fire managers at the Denali National Park and Preserve. We will collect lake sediment cores from sites in the park to reconstruct fire history and vegetation feedbacks spanning the Holocene to provide critical baseline information on boreal burning for ongoing fire management.
