Caitlyn Hall
CBBG Student Leadership Council President

Caitlyn A. Hall is the President of the CBBG Student Leadership Council.  She is a graduate student at Arizona State University, seeking a PhD in Environmental Engineering.  Her topic is Biogeochemical Reactive Transport Modeling of Microbially Induced Desaturation and Precipitation via Denitrification (MIDP).  Her advisors are Dr. Bruce Rittmann and Dr. Ed Kavazanjian. 

Student Research Summary:  The primary objective of my work is to develop a predictive model to consider environmental biochemical effects and subsurface flow patterns on the delivery of substrate and MIDP product formation to the soil at risk of liquefaction.  Though MIDP has been shown to be effective in mitigating liquefaction in laboratory conditions, little has been done to investigate up-scaling of this technology for near-term applications.  Environmental conditions found in the field will introduce engineering challenges and affect process deployment and outcomes.  These should be investigated further and considered to improve prediction accuracy and process optimization.  Therefore, the substrate components and their interaction with biogeochemical and hydromechanical properties in the soil need to be explored and understood.  These developments are to be implemented in the developed predictive tool, such that field deployment of this treatment strategy and its subsequent mechanical effects can be estimated.  The resulting multiphase reactive transport biogeochemical model will then be validated using experimental data.
