Major Focus Areas of Research

  • Biomimetics of energy efficiencies for indoor environments

    This is an interdisciplinary theme involving the physiology expertise of biologists (including both botanists and zoologists), image analysis expertise of computer scientists, heat transfer and transport expertise of mechanical engineers, and geotechnical expertise of civil engineers. Our objective is to learn from the natural evolution of thermoregulatory behavior of human skin and plant leaves and apply that knowledge to design Geodermis, a system of natural and sustainable materials including soils and plants, for use in human-built environment to minimize energy needed for heating and cooling.

  • Integrated Research and Education: Synergisitc Incorporation of Humanities in Engineering Curricula

    Partnerships with researchers from education and learning science led to NSF-funded ventures on design of geoenvironmental engineering as an interdisciplinary curriculum at Kansas State. Subsequent efforts in this focus area include development of broad engineering curricula where humanities and social sciences are presented to students, not as fragmentary principles, but as non-technical dimensions of engineering principles. Proposals submitted in this area are currently being reviewed by the NSF.

  • Physicochemical and Biological Mechanisms of Pore

    Another interdisciplinary theme involving chemical engineers and biologists, this area of research focused on colloid particle transport, deposition, and re-entrainment mechanisms in porous media. The research was later extended to: i) “Facilitated transport” of contaminants in soils, ii) Piping and self-healing of cracks in levees, earthen dams, and embankments, iii) Liner behavior in waste lagoons, etc.

  • Immiscible Fluid Phase Dynamics

    Started out as a simple study dealing with clean-up of contaminated sites, this research evolved into a highly interdisciplinary theme over a period of fifteen years involving collaborations with physicists, mechanical engineers, mathematicians, and computer scientists. In its latter phase, funded by NASA, this research identified the basic mechanisms of immiscible fluid (air) dynamics under micro- and zero-gravity conditions.

  • Basic Research on Upscaling Using Fractals, Random Networks, and Stochastic/Uncertainty Analyses

    This theme focused on developing methods that allow upscaling of properties from micro- to lab- to field-scale using fractal systems and random networks. Another dimension of this theme was to employ First-Order Second-Moment (FOSM) methods and Kalman filters to characterize the uncertainties in predictive modeling, intrinsic uncertainties in system parameters, and modeling errors.
