General Information

Title:Professor & Vice Dean for Teaching Affairs

Discipline area:Oral Pathology



Research profiles

1. The growth and behavior of odontogenic lesions of the jaws, which mainly involves surgical pathology of odontogenic cysts and tumors, molecular pathogenesis of odontogenic lesions and mechanisms of bone resorption caused by aggressive odontogenic lesions.

2. Inter-/ intra-tumor heterogeneity by sequencing both the whole genome and transcriptome of microscale tissue regions in a number of oral malignancies using histology guided micro-dissection technique.
