My research interest is in geotechnical and geoenvironmental engineering. I just concluded a study sponsored by the National Science Foundation (NSF) to understand the effects of surfac blasts on underground structures and evaluate various methods to mitigate such damage. Both numerical analyses and physical model tests using a geotechnical centrifuge are part of this study. In a prior study, also sponsored by the NSF, I was able to measure strains induced on a model underground tunnel or a pipeline due to blasts at the ground surface, using geotechnical centrifuge modeling techniques.
I have also conducted research into various aspects of landfill design, such as geosynthetics, slope stability, seismic response, settlement, and contaminant migration. I am part of an ongoing study (also funded by the NSF) in which we are attempting to characterize the effects of an earthquake on layered soil below ground surface, using instruments embedded in the ground.
