Nadia's research bridges the fields of climate science, paleoecology, and statistics to investigate past climate changes and variability, in turn, to better understand current climate change and improve our ability to predict future changes. She utilizes biomarkers and geochemistry preserved in lake sediments, peats, and soils to assess how terrestrial and aquatic environments have responded to local- to global-scale climate change and variability. She also combines climate model simulation outputs and climate reanalysis with paleoclimate data to investigate mechanisms controlling past, current, and future hydroclimate variability. Her work spans from local (e.g., individual lake) to global (e.g., climate change and variability) spatial scales and from sub-seasonal (e.g., lake temperature modeling) to millennial timescales (e.g., regional hydroclimate signal decomposition).
