Research interests: 
  • The impact and controlling mechanisms of large-scale cyclic paleoenvironmental change during the Silurian interval

Dr. Andrew Caruthers is a senior research associate at the Michigan Geological Repository for Research and Education at Western Michigan University. He is working on a variety of projects in western North America and enjoys incorporating graduate students into his work. Caruthers uses a combination of invertebrate paleontology and carbon-isotope chemostratigraphy to explore the dynamics of mass extinction and paleoenvironmental change. A primary goal of his research at MGRRE is to use these tools to investigate problems associated with correlating the Silurian subsurface stratigraphy of the Michigan Basin.
