Research Experience

2013 Principal investigator of development of a sinkhole warning system under a building using TDR technology.

1993 Analytical modeling of the response of transmission pipelines to ground movement for the U.S. Bureau of Mines.

9/79 to 9/93 Involved as Technical Director in funded research on mine subsidence related projects. Most of this work is in cooperation with The University of Illinois. The scope of the projects range from analysis of: the short- and long-term stability of the mine structures and overburdens; the nature and magnitude of subsidence movements in the overburden and on the surface; the behavior of surface and underground structures to subsidence; subsidence damage prediction; design and implementation of abatement procedures against hazards from subsidence as well as development of advanced reconstruction procedures for homes damaged by subsidence.

10/76 to 9/78 As a Research Engineer involved in the evaluation of geophysical data for assessment of geologic and geotechnical site conditions. The geophysical data was collected from field test sites by using borehole radar and acoustic sensors.
