Oral Molecular Bioregulation

Introduction

It is rare for diseases of the mouth (oral diseases) to produce life-threatening symptoms. However, oral diseases do cause a considerable drop in quality of life (QOL). Additionally, it is characteristic for systemic diseases to produce symptoms in the mouth and for oral diseases to produce symptoms throughout the body. Our laboratory works day and night to use immunology, molecular biology, and pharmacology to uncover the "mysteries" of these diseases. We then use this foundational research to take the first steps toward developing safe and effective prevention and treatment methods.

Our laboratory is composed not only of graduates from the school of dentistry but a staff of diverse backgrounds to seriously wrestle with our research. We openly welcome graduate students with an interest in the "mysteries" of life science, including those in dentistry. We are accepting many graduate students from clinical fields aspiring towards foundational research.
