What We Do

The Lee lab concentrates its research efforts to explore diverse approaches for oxidation-based water remediation, develop advanced materials and systems for markedly improving water treatment efficiency, and investigate redox chemistry that is fundamental to degradative reaction pathways. Specific research interests include: (1) developing new persulfate activation processes utilizing nanoscale metal- and carbon-based materials and comprehending the mechanism behind persulfate activation; (2) designing the visible-light-responsive systems based on new photosensitizing and photocatalytic nanomaterials (e.g., fullerene and porphyrin derivatives, bismuth- and silver-based catalysts) and evaluating their capacity for oxidative degradation and disinfection; (3) exploring electrochemical and photo-electrochemical oxidation processes for treatment of emerging contaminants and reduction of organic carbon and ammonia nitrogen; and (4) applying oxyanion photolysis for organic decomposition and unveiling the relevant mechanisms using laser flash photolysis. Research work in our lab requires the integration of knowledge from the multiple sectors of applied science and engineering (e.g., chemistry, material science, environmental engineering, and chemical engineering). Collaboration with researchers from various research areas is critical to our research activity: synthesizing innovative materials, analyzing and optimizing processes, and investigating mechanisms in depth. Accordingly, we are always happy to hear from potential colleagues and students who take active interest in addressing environmental issues by an interdisciplinary approach.
