FORMACIÓN

• Cirujano-dentista (1994), en la Facultad de Odontología de Piracicaba, Universidad Estatal de Campinas;
• Maestro (1996), en Biología y Patología Buco-Dental de la Universidad Estatal de Campinas;
• Doctor (1999), en Biología y Patología Buco-Dental de la Universidad Estatal de Campinas;
• Post-Doctorado (2002-2004), de la Facultad de Ciencias Médicas, Universidad de Colorado, USA.

ÁREAS DE INTERÉS

• Comprender los mecanismos biológicos y genéticos relacionados al cáncer de boca, particularmente entender la participación de los genes homeobox en la tumorigénesis oral y determinar la influencia de los miofibroblastos del estroma tumoral en los fenotipos relacionados al cáncer, incluyendo proliferación e invasión celular.
• Analizar los aspectos clínicos, epidemiológicos, genéticos y moleculares de las enfermedades genéticas y síndromes con compromiso orofacial, con particular énfasis en el estudio de polimorfismos genéticos en fisuras labio-palatinas.
• Caracterizar los mecanismos biológicos y determinar los defectos genéticos de los aumentos gingivales inducidos por ciclosporina A y los heredados como fibromatosis gingival. En un futuro próximo identificar moléculas y terapias definitivas para los aumentos gingivales.
