Teaching

Along with the rest of the dental materials team, I teach dental materials to UG and PG students and supervise the research projects.

Research

Research Interests:

I am working in the area of dental and biomedical materials. I use solid-state nuclear magnetic resonance (NMR) spectroscopy to investigate structure of these materials. This technique is powerful and informative to resolve the structure of amorphous and crystalline solids. We study structure of bioactive silicate and phosphate glasses containing halogen and other components. We investigate the setting reactions in dental materials using solid-state NMR among other techniques. We study structure and properties of dental glass-ceramics and various substitutions in apatites. Using solid-state NMR and in combination with other techniques, we study structure of teeth, bones and other natural apatites. We apply our knowledge on structure of natural and synthetic materials for development future materials for specific applications.
