Fractured Rock & Groundwater Modeling

I started doing fractured rock modeling when I was working at Oak Ridge National Lab (ORNL) and conducted research on radioactive waste sties. Since joining Temple, I have focused on hypothetical models and fractured rock tracer tests.

FUNDING: Some funding has come from the NSF-CZO sites but also includes work has been hypothetical modeling that did not require research grants.
