  • Boadu, Fred K., Associate Professor (joint with Civil and Environmental Engineering)
    Research Interest: My research seek to develop an understanding of how the engineering, environmental and petrophysical properties of porous media (soils, fractured rock, biological tissues) affect measurable geophysical responses, and subsequently develop methodologies by which these properties can be obtained from non-invasive geophysical measurements. These goals are pursued by developing basic theoretical models, then increasing their order of complexity I perform laboratory and field measurements, and compare these data to the outputs of the theoretical models. This pursuit will lead to the integration of theory and laboratory or field data for reliable and accurate prediction of subsurface (porous medium) properties and saturation conditions from geophysical information. The same approach is used to assess the stability and strength of geo-materials in the subsurface - mudslides, landslides, liquefaction etc. Bio-materials, for example, biologically contaminated soils or tissues essentially can be considered as multi-phase fluid saturated porous system. Changes in the biochemical and physiological conditions of these materials induce frequency dependent spectral responses which can be quantified. Such quantification can lead to characterization and monitoring of their engineering and environmental behavior over time. Research in methods to explore for hydrocarbons by development of petrophysical models, and extraction reservoir properties using fractal and neural network concepts is also undertaken
    Current Projects: Nitrate Contamination in groundwater Petrophysical modeling - Integrated electrical and seismics methodologies Characterization of fractured media Neural Network and petrophysical properties of uncosolidated media

  • Dolbow, John E., Yoh Family Professor of Engineering and Associate Professor of Materials, Structures & Geosystems
    Research Interest: Modeling quasi-static and dynamic fracture of structural components, the evolution of interfaces with nonlinear constitutive laws, and developing models for stimulus-responsive hydrogels

  • Gavin, Henri P., Associate Professor and Bass Fellow of Civil and Environmental Engineering and Professor in the Department of Civil and Environmental Engineering
    Research Interest: Structural dynamics, structural control, and related applications of controllable materials, especially the use of electrorheological and magnetorheological dampers for structural vibration suppression. This work encompasses rheology, non-Newtonian fluid mechanics, visco-elasticity, non-linear structural dynamics, and multivariable control.
