Welcome to the SIPERG. I am a broadly trained geologist who is interested in using geochemical and sclerochronological techniques to document (and better understand) changes in Earth’s climate system. Although I mainly work in the northern North Atlantic Ocean within the most recent millennium, I am interested in other timescales and geographic regions. We have several exciting research projects that are underway, so if you would like to know more about us, and our research group, please contact me.
Suzanne Ankerstjerne- Lab Manager: email- email@example.com
I am the lab manager for the Stable Isotope Laboratory in the geology department. My duties include coordinating and scheduling activities within the lab and maintaining the resources necessary to complete quality stable isotope measurements. I enjoy working with students, Iowa State faculty, and other scientists to obtain high quality data.

I am a science enabler specializing in geological field work. My field areas have varied from dinosaurs in Mongolia to early hominids in East Africa. Current projects are Eocene primate sights in the Western Desert of Egypt and Glacial movement in Norway. My research interests are anything with geology and technology. I work for the Department of Geological and Atmospheric Sciences at Iowa State University as an IT and lab support person. Also, I help maintain the analytical equipment in the stable isotope lab and I assist in running our geology field camp in the Bighorn Mountains.

I am a PhD candidate at Iowa State. My project involves using Arctica islandica shell-growth chronologies and annually resolved oxygen isotope records to reconstruct marine environmental variables in the arctic, specifically in response to the North Atlantic Oscillation/Arctic Oscillation across the northern hemisphere Medieval Warm Period/Little Ice Age/Modern Climate transitions. I graduated from Macalester College in 2010 with a major in Geology major and a minor in Environmental Studies.

I am a MS student in my first year at Iowa State University working with Dr. Alan Wanamaker. I have my BS degree in meteorology from ISU with a minor in chemistry. My project involves studying speleothems from a cave in Portugal (behind me in this picture) to develop a decadal-scale paleoclimate record of hydroclimate and atmospheric variability during the late Holocene.
