Tim grew up on the Rockdale Run Formation, with a sinkhole in the backyard of his home (which may account for his continued interest in karst).  He has taught Geophysics, Karst Hydrogeology, Geocomputation, Engineering Geology, Petroleum Geology, and Environmental Geology and Science Teaching at F&M, and formerly the University of Pennsylvania and Drexel University.  Tim is an Associate Editor for the Journal of Sensing and Imaging, and Hydrogeology Journal, and a member of the Karst Commission of the International Association of Hydrogeologists.  He is also a member of international scientific collaborations that are funded by the North Atlantic Treaty Organization, Science for Peace and Security (NATO SPS) program, the US-Russia-Japan-EU International Science and Technology Center (ISTC), and the Russian Foundation for Basic Research (RFBR) to study novel technologies for humanitarian de-mining, remote detection of disaster victims buried beneath rubble, avalanches, etc., and non-destructive subsurface testing for historic and cultural preservation.  He is a founding principal (with his wife Felicia) of Enviroscan, Inc., a geophysical contracting firm.  He now lives with his wife and dog (and formerly three now-launched kids) on the Conestoga Formation (with no sinkholes…yet) in Lancaster.
