Todd Thompson is the director of the Indiana Geological and Water Survey and the state geologist of Indiana. His areas of research have been on the architecture of ancient carbonate shoals and its relevance on recoverable dimension stone, the impact of seismicity on Wabash River drainage behavior and the stratigraphy of middle Mississippian sediments in south-central Indiana. But most of his work has been on past lake-level change in the upper Great Lakes and concomitant shoreline behavior.
Thompson received his undergraduate degree from Allegheny College and his master’s and doctoral degrees from Indiana University.
