Most of my research activities today have their basis in photobiology: Antimicrobial photodynamic therapy as an alternative to the use of conventional antibiotics to treat oral infections; adverse reactions in tissues/cells due to exposure to exogenous/endogenous chemical substances combined with optical radiation; optical radiation protection in the dental clinic.
