Welcome! The OSU ice core lab studies past climate and biogeochemical cycles to understand how the earth system worked in the past, and how it might change in the future. Current projects investigate past variations in greenhouse gases, chronologies of ice cores and glacier variations, and very old ice cores in Antarctica, through our work in COLDEX, the NSF Science and Technology Center.  We conduct field work in polar regions and do lots of laboratory geochemistry.  If you are a prospective graduate student or postdoc, or an undergraduate looking for a research project, see prospective students.
