Prof. Du's research focuses on using computer simulations and materials modeling methods, often in combination with advanced materials characterizations, to understand the structure and structural origin of properties of materials with complex structures. He is interested in studies of glasses, ceramics, and nanostructured materials, as well as defects, surfaces and interfaces in these materials with microelectronic, energy, environmental, and biomedical applications. His current interests include bioactive glasses, nuclear waste glasses, glass corrosion, solid state electrolytes, low-k dielectrics, and electronic ceramics.
