Interests

Primary interest is in basic biology and pathobiology of salivary glands. Previously characterized ion channels and calcium signaling components in gingival keratinocytes and salivary gland cells; and their alteration or activation in interactions with Porphyromonas gingivalis (in collaboration with former faculty member Dr. Richard Lamont, now at the University of Florida, Gainesville). Earlier and renewed studies involve salivary changes in Graft versus Host and other diseases.
