Research in IPL focuses on using isotopologue* distributions, mostly involving carbon or oxygen, to understand Earth system processes. Much of our current research revolves around measurements of clumped isotope distributions in carbonates and triple oxygen isotope distributions in waters and common Earth surface materials (e.g. carbonates, bioapatites). Ongoing projects include studies of paleoclimate in the Western United States, eastern Africa, the Peruvian Andes and anywhere else with good problems that we can tackle.
*What are isotopologues? They’re molecules that differ from each other in their distribution of isotopes.
The best way to get a sense for our current research activity is to check out the abstracts of presentations by members of our group and/or with data from the lab – see below for listing and links.
For published papers check out the IPL Publications or the pages of IPL group members. If you’re looking to find abstracts from projects done in the earlier iteration of the lab, at Johns Hopkins, check out this legacy website from the JHU lab.
