Research Statement
The goal of my research is to develop minimally invasive, biologically based therapies for inflammatory dental diseases. I have particular interest in investigating the link between pain, inflammation and regeneration as well as the implications of dental disease on general health. The current research programmes include:
1- Exploring potential strategies for optimal differentiation of dental pulp stem cells with particular focus on inflammation and its impact on regeneration
2- Developing in vitro and in vivo models to study neuronal signalling in inflammatory and neuropathic pain
3- Investigate potential links between dental infections, systemic inflammation and general heath.
