My research focuses on the surprising variety of flow patterns we discover in multiphase, granular, and complex fluid flows. We study how large-scale flow patterns emerge from a combination of the microstructure of the fluid, and the viscous, capillary, frictional and gravitational forces acting on the system. Our results provide explanations for naturally occurring phenomena in geophysical flows, and helps optimise engineered processes such as soil remediation, oil and gas recovery, and carbond dioxide cature and storage.

Teaching

  • EG-169 Environmental Awareness for Engineers

    The module focuses on the environmental impacts of human activity, industry, and energy consumption. With the global population soaring past 7 billion in an increasingly industrialized world, human activity is now affecting energy and material balances on a global scale. The next generation of engineers must appreciate the environmental impacts of current technology in order to engineer better solutions for the future.

  • EG-216 Practical Environmental Chemistry

    This environmental chemistry laboratory module is designed to give relevant experimental experience to environmental engineers. The module aims to develop skills in experiment design; the appropriate use and safe handling of chemicals, the acquisition, processing, error analysis, and interpretation of experimental data; and to develop skills in presentation and communication of experimental and technical information. The practical class consists of an introductory lecture, six environmental engineering 4 hr labs, followed by one poster session, at which each student presents a poster on one of the experiments.

  • EGCM40 Pollutant transport by groundwater flows

    This module focuses on groundwater flow in aquifers, the transport of pollutants by groundwater flows, and the chemical and biological transformation of pollutants in the subsurface.
