Research in the Petersen Group focuses on reconstructing past climate using geochemical tools, in particular, stable and clumped isotopes of carbonate. 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 is looking to expand!
We are recruiting both graduate and undergraduate students for the coming year.
Graduate: Applications to UM Earth and Environmental Sciences Department graduate program are due in January 2019. Contact Dr. Petersen if you are interested in applying. More info can be found here.
Undergraduate: We are also recruiting undergraduate students for the 2018-2019 academic year and beyond, either directly or through the UROP program, where we have multiple open projects posted. Interested students should contact Dr. Petersen through the UROP program. Enthusiastic and driven undergraduates outside of the UROP program should contact Dr. Petersen directly.
