My name is Pete Puleo and I am a fifth year PhD candidate at Northwestern University in the Department of Earth and Planetary Sciences. I work with Professor Yarrow Axford as a member of the Quaternary Sediment Lab. I am passionate about educating others about Earth Science and past, present, and future climate change. My expertise is in Earth System Science and Earth’s climate history. I am actively searching for a teaching-focused position starting in Fall, 2024.
I have completed research projects focused on 1) reconstructing the hydroclimate of midwestern North America over the last ~14,000 years, 2) evaluating the duration, seasonality, and magnitude of abrupt climate change during the Younger Dryas (~12,900-11,700 years ago) in south Greenland, and 3) determining how a south Greenland outlet glacier advanced/retreated in response to climate change over the last ~11,000 years. To create these records, I used a combination of stable oxygen isotope measurements on biological remains taken from lake sediment cores along with measurements of bulk sediment chemistry, lithology, and grain size. Understanding how climate and glaciers have changed in the past provides context for how they might change in the future.
