Research in the Petersen Group (SCIPP Lab) focuses on reconstructing past climate using geochemical tools, in particular, stable and clumped isotopes of carbonate fossils. We have ongoing projects focusing on reconstructing climate in the Cretaceous, Miocene, Pleistocene and other time periods, looking at how climate has changed on million-year down to sub-annual timescales. Check out our Research page for more details.
The Petersen Group/SCIPP Lab operates out of the University of Michigan Stable Isotope Laboratory – a three-PI lab (PI’s Petersen, Lohmann, and Cole). Our lab was recently renovated top-to-bottom and we moved in to the new space in March/April 2019.
Within the Stable Isotope Lab, the Petersen Group is primarily making clumped isotope measurements. We have two mass spectrometers operating: Old Blue, a Thermo MAT 253, where samples are prepared on a manual off-line preparation device, and Maisie, a Nu Perspective with NuCarb automated carbonate preparation device.
Interested in joining the Petersen Group?
We will be recruiting new graduate students for enrollment in Fall 2021. We will consider excellent candidates for both the MS and PhD programs, but with greater emphasis on PhD applicants.
Graduate: Applications to UM Earth and Environmental Sciences Department graduate program (Masters and PhD) are typically due in January to begin the following fall semester. Contact Dr. Petersen if you are interested in applying. Please include your CV and unofficial transcript with your email. More info can be found here about the admissions process.
Undergraduate: The SCIPP lab has traditionally had a number of undergraduates working in our lab (see People), recruited either directly or through the UROP program. Unfortunately, we will not be taking on new undergraduate researchers in Fall 2020. At the moment, new undergraduate researchers are not permitted into the lab where we typically employ them doing sample prep. Check back in January 2021 as the lab reopening progresses.
