My present focus is on 1) faults, fractures, folds and tectonics in the Appalachian Basin, 2) the tectonics of the Appalachian Orogen, 3) the relationships between the basin and the orogen, and 4) drivers of seismicity in the basin. The data sets that I integrate for a better understanding of the basin and orogen are seismic reflection data, FMI logs and other borehole imaging systems, core, extensive field work (47 years of sed, strat, structure), gravity, magnetics, seismicity and in the past, geochemistry.
