Dr. Isabella Brunner is a postdoctoral researcher at the Hague Program on International Cybersecurity. Having obtained her PhD in international law, her research focuses on questions of how international law applies to cyber operations, in particular the law of state responsibility and the law of international organizations. With a background as a legal officer at the Austrian Foreign Ministry, she regularly provides legal consultations to the MFA on cyber issues. Most recently, she drafted the Austrian position on international law applicable to cyber activities. Isabella’s academic journey includes researcher and lecturer roles at the University of Vienna and Bundeswehr University Munich. She also worked for the Ad Hoc Committee on Cybercrime at UNODC as a JPO and received a Fulbright stipend to study at NYU School of Law.
