Associate Professor at Oral Biology Department, Faculty of Dentistry, Universitas Gadjah Mada. My researches focus on the characterization of mucosal cytology. I’m currently working on the effect of hormonal contraceptive on oral mucosa especially on the expression of its differentiation marker and the characterization of oral mucosa. I’m also interested in studying the effect of aging on oral mucosa and biological response of oral tissue after the application of certain herbal products.
