I serve as a quaternary geologist and am the STATEMAP program coordinator. I research and conduct field investigations on the quaternary deposits and stratigraphy of Iowa, with a primary focus on the pre-Illinoian glacial till units and development of the Iowan Erosion Surface. I collect, describe, and analyze surface and subsurface geologic samples and interpret the results for use in surficial mapping, Quaternary stratigraphy, and hydrogeological studies. I also respond to information requests on the geology of Iowa and take part in a variety of educational and outreach activities.

Research interests:

• Quaternary stratigraphy in the state of Iowa and how these deposits can improve our understanding of regional environments and past climate
• The development of the Iowan Erosion Surface and its relationship to loess deposits in Iowa
