Dr. J.I. Gerhard - Research Interests

Contaminant Hydrogeology

Scientific understanding of groundwater flow, contaminant transport, and biogeochemical processes occurring in the subsurface. Engineering design and application of remediation systems for improved water quality.

Multiphase Flow in Porous Media

Understanding and accurately simulating the migration of non-aqueous phase liquids, such as chlorinated solvents and PCBs, simultaneously with gas and water phases through porous media. Focus on laboratory and numerical studies of the contamination of drinking water aquifers by hazardous industrial liquids.

Innovative Methods of Remediating Soil and Groundwater

Self-sustaining Treatment for Active Remediation (STAR) is a new remediation technology developed for soil contaminated with hazardous organic industrial liquids. ‘Self-sustaining smoldering’ is a highly controlled burning reaction - similar to charcoal in a BBQ. As a remediation technique, it destroys NAPLs embedded in soil while simultaneously generating enough energy to propagate itself through the subsurface.

Geophysics for Mapping Subsurface Remediation


Engineering for Sustainability

Increasing the breadth and depth of engineering education to equip engineers with the tools required to lead society towards more sustainable practices. The Reinvent the Toilet Challenge, funded by the Bill and Melinda Gates Foundation, aims to develop a transformative technological solution to human waste.
