Chih-Ko Yeh, Ph.D., BDS



Dr. Yeh’s research is focused on studying the effect of aging on oral health, with a special emphasis on saliva and salivary gland biology/physiology. These studies include: 1) monitoring saliva function in clinical samples from aging, hypertensive, and diabetic stratified populations, as well as HIV infected patients, 2) exploring the pathogenesis of age-related oral and salivary gland diseases, and 3) salivary gland regeneration/repair with stem cells using genomic and proteomic approaches. Most recently, his laboratory has been involved in several translational studies developing saliva-based diagnostics for MI and cancer detection using nanotechnology and effective, long-term anti-fungal (specifically, anti-candida) denture materials.  Dr. Yeh’s laboratory contains all necessary equipment and resources for performing modern chemistry, physiology and molecular and cell biology studies.
