I am full professor at ENSICAEN (National school of engineering) and I work in the GREYC research laboratory. I lead the computer science department at ENSICAEN. I also lead the "E-payment & Biometrics" research unit in this lab.

My research activities concern biometrics. I work on the developement of biometric systems (face, fingerprints, keystroke dynamics, touch screen interaction, palm veins...), multibiometrics (score fusion), the evaluation of biometric systems (performance, security, user perception), the quality of biometric templates (image and pattern quality) and the protection of biometric data for privacy applications (example of cancelable biometrics using fingerprints).
