Education

• Ph.D. University of Illinois, 1996
  
• A.B. Colgate University, 1988
  

Research Interests

• Stratigraphy, paleoclimate and paleoenvironment of Illinoian and pre-Illinoian sediments and paleosols in SW Illinois
• Provenance of loess and lake sediment records, based on mineralogy, magnetic properties and elemental composition
• Utilization of magnetic susceptibility for delineation of hydric (wetland) soils and for ecological restoration
• Geomorphology and history of Illinoian glaciation in Illinois

Current Research Projects

• Surficial geology mapping in the Kaskaskia River Basin in southwestern Illinois
• Correlation of soil magnetic suscepitability to distribution of native tree and prairie species; utilization in restoration
• Comparision of paleoclimate and paleoenvironment of Wisconsinan, Illinoian and pre-Illinoian deposits in SW Illinois based on fossil assemblage, mineral and magnetic methods
