Leonid Polyak studies the geological history of the Arctic Ocean, focusing on how past ice sheets, glaciers, and ocean currents shaped the seafloor and its sediments over the last few hundred thousand years (the Pleistocene and Late Quaternary periods). This work relies on analyzing sediment cores, sonar mapping, and chemical and isotopic tracers to reconstruct ancient glaciations, ocean circulation, and climate change in the Arctic. Prospective students would likely engage with marine geology, paleoclimate reconstruction, and dating techniques applied to Arctic Ocean sediment records.

Publication output has been variable but continuing over the last decade, with a high in 2017, a lull around 2020 and 2023, and a modest, steady rate of a few papers per year in recent years (2022-2025).
