Welcome!

My research program is focused on the evaluation of groundwater hydrologic interfaces.  The implementation of this research agenda has involved the evaluation of highly localized systems and more broad scale watershed processes.  This research direction has allowed me to participate with and develop strong multi-disciplinary teams.  Please feel free to contact me with questions about my research program and the multi-disciplinary teams with which I participate.
