 Gary Curtis is a hydrogeochemist who develops and applies reactive transport models to simulate groundwater contamination problems involving hexavalent uranium (U(VI)) and chloroethenes.  His research interests include: Developing and applying conceptual models for simulating reactive transport processes in groundwater;Conducting nonreactive and reactive tracer tests to characterize subsurface physical heterogeneity and effective reactive processes; Quantifying prediction uncertainty inherent in all reactive transport models;and, Developing upscaled reactive transport models that can be applied to real-world plume scale simulations that honor detailed understanding developed from small scale laboratory and field tracer tests.
