Professor Loeb’s research efforts span the intersection of materials science and environmental engineering, with particular focus on the removal of chemical and biological contaminants in water using sunlight, engineered light sources, and light-activated nanomaterials. Her recent research has aimed to characterize how sunlight inactivates challenging viruses in the environment, such as norovirus and the novel coronavirus. She is also interested in the fabrication and design of novel light-activated nanomaterials for sustainable water disinfection, and developing improved methods for detecting and quantifying pathogens in water.
