Education
Attended Wabash College, Purdue University (B.S. 1983), Indiana University (M.S. 1987, Ph.D. 1994).
Received a B.S. from Purdue University with a geology major and mathematics minor.
Received a M.S. from Indiana University with a major in hydrogeology and a minor in numerical methods. The M.S. thesis used numerical modeling to verify field evidence of ice-sheet surging during the Pleistocene epoch.
Received a Ph.D. from Indiana University with a major in hydrogeology and a minor in geochemistry. The Ph.D. dissertation used hydraulic and geochemical modeling to determine that hydrated iron-sulfate minerals were responsible for acute acid-mine drainage events.
Horizontal Borehole Flowmeters
Horizontal borehole flowmeters may provide opportunities to measure the rate and direction of groundwater flow and the advective transport of dissolved and neutrally buoyant contaminants. Optical, acoustic, thermal, and chemical technologies are being evaluated. Research is directed toward defining the limits of each technology and the environmental and hydrologic conditions that are best suited for each tool. Testing has been done in field settings and laboratory aquifer simulators.

Episodic Master Recession Model Output used for Recharge Estimation in a Rain Garden on Sandy Soil, Gary, Indiana, 2016-18
A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration, and divert stormwater from city sewers. In order to investigate the impacts of the installed SCMs, hydrologic data were collected prior to and following the installation to estimate site water budgets (Lampe and others, 2022).
