Our research integrates coordination chemistry, nanomaterials synthesis, advanced characterization techniques, and environmental process engineering, providing students and researchers with opportunities to work in a multidisciplinary and collaborative research environment.
The Inorganic and Materials Chemistry Research Group conducts interdisciplinary research at the interface of inorganic chemistry, nanotechnology, and environmental science. Our work focuses on the design, synthesis, characterization, and application of advanced materials for sustainable environmental solutions, particularly in the area of water quality assessment and wastewater treatment. The group develops innovative inorganic materials and nanostructured systems to address critical global challenges, including water pollution, emerging contaminants, and resource sustainability. Through fundamental and applied research, we aim to translate laboratory discoveries into practical technologies that contribute to sustainable water management and environmental protection, aligned with Sustainable Development Goal 6 (Clean Water and Sanitation).
