Gu's general research is in water quality and environmental health. She specifically focuses on the following areas: (1) apply biotechnology to improve and develop more sustainable wastewater treatment and remediation processes to maximize nutrient recovery and, minimize the energy consumption and carbon footprint; (i) investigate the impact of climate change on global phosphorus cycling, particularly biological processes, and associated implications in phosphorus utilization efficiency in agriculture; (iii) develop next-generation toxicogenomics-based toxicity assessment technology platform, in combination with data science, to enable risk-based water quality monitoring and technology efficacy assessment, and to elucidate the causal environmental matrices.
