As the Director of the Indiana Geological Survey and State Geologist of Indiana, Todd Thompson serves as chief executive of the institution, providing overall leadership in fulfilling the mission in directed research, service, and education. Todd has worked at the Indiana Geological Survey for more than 25 years in a number of different capacities. 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. Most of his work, however, has been on past lake-level change in the upper Great Lakes and concomitant shoreline behavior.

Todd received his undergraduate degree from Allegheny College and his master’s and doctoral degrees from Indiana University.

Specialties:
Hydrogeology, carbonate geology, cave and karst science (speleology), stable isotope geochemistry, carbon transport in the critical zone, environmental geophysics, geothermal systems

As the Assistant Director of Research, Lee coordinates and supports the research activities of IGS staff through project and editorial management and active collaborations. Lee is a licensed professional geologist in Indiana and Kentucky with two decades of professional experience in academic, government, and industry jobs. His scholarly activities span the natural sciences as they pertain to the understanding of carbonate aquifers—groundwater that influences the drinking water of one out of every four people on Earth. An avid caver, cartographer, and a certified advanced diver, Lee has visited and surveyed caves in 30 states and several countries in Europe, Asia, and the Caribbean. His current research questions focus on carbon transport in the critical zone, and includes funded research programs in Indiana, Kentucky, Miami, Mt. Rainier, and Romania.

Lee arrived at IGS after 8 years as tenure line faculty in Kentucky and Indiana. He is a Romania Fulbright Fellow and a USGS Mendenhall Postdoctoral Scholar. He received his PhD from the University of South Florida and his MS from the University of Missouri-Columbia. His undergraduate in Physics and Mathematics is from Western Kentucky University.

Shawn Naylor

Director
Director: Center for Geospatial Data Analysis
phone:
(812)855-2504

specialties:
Unsaturated zone hydrology, glacial aquifer systems, hydrologic monitoring, digital elevation model (DEM) analysis

Shawn Naylor is a Research Hydrogeologist and Director of the Center for Geospatial Data Analysis (CGDA), a research group that bridges the IGS, IU Department of Geological Sciences, and IU Department of Geography. Prior to joining the CGDA, Naylor gained professional experience in both the private and public sectors while working on projects ranging from contaminated aquifer characterization/remediation to mapping irrigated agricultural lands using geographic information systems (GIS) and remote sensing. He earned an MS degree in geology from the University of Montana where he studied alpine glacial geology and landscape evolution. His current research interests include quantifying water and heat fluxes through the unsaturated zones of glaciated terrains, characterizing glacial aquifers in three dimensions, and developing spatial databases to facilitate geothermal energy exploitation in Indiana.
