Nicolas Diaz Ferreyra arbeitet derzeit in den Bereichen nutzbare Privatsphäre und Sicherheit. Er ist Teil des Graduiertenkollegs USCM. Seine Forschung beschäftigt sich mit der Entwicklung von benutzerzentrierten Technologien für die Risikokommunikation und die Sensibilisierung der Privatsphäre in Sozialen Netzwerken. In seiner Doktorarbeit bringt er interdisziplinäres Wissen aus der Informatik und der Medienpsychologie zusammen und konzentriert sich auf Fragen der Benutzerfreundlichkeit, des Risikobewusstseins und der Ethik auf sozialen Plattformen. Aktuell untersucht er den Bereich  selbstadaptiver Technologien in Sozialen Netzwerk Apps, sowie präventive Technologien für diese. Seit August 2018 ist er Teil des H2020 Projektes "PDP4E: Methods and Tools for GDPR Compliance through Privacy and Data Protection Engineering".
