Leonid Polyak studies the geological history of the Arctic Ocean by analyzing seafloor sediment cores to reconstruct past ice ages, glacier movements, and ocean circulation patterns over hundreds of thousands to millions of years. This work helps scientists understand how Arctic ice sheets and ocean currents have changed in the past, which provides context for interpreting current climate change. Students working with him would likely engage with marine sediment analysis, paleoclimate reconstruction, and Arctic Ocean geological history.
Publication output has slowed in recent years, dropping from a peak of 5 papers in 2021 to a low or single-paper output in 2023-2025, with a five-year average of about 1 publication per year.
