Research Interests
My research interests focus on dissecting molecular pathways relevant to developmental disorders that affect craniofacial and dental systems as a result of genetic abnormalities or inflammation. Our primary research approach is centered on functional genomics. Our recent work highlights the unique role of amelogenin, dentin sialophosphoprotein, and TGF-beta1 in tooth development and disease, and the novel role of cyclin dependent kinase-5 (Cdk5) in neuronal functions such as nociception and pain.
