This research focuses on developing materials and techniques for the electrochemical detection of low concentrations of pollutants such as heavy metals and disease biomarkers like glucose. Motivated by the Navajo Nation's history of uranium mining and modern extraction activities like fracking, this area aims to create low-cost detection methods to monitor contaminants and address health issues, including obesity and type 2 diabetes. It also involves fabricating and testing electrodes and developing microfluidic laboratory models for soil contaminant flow and detection.
