I am currently a Lecturer (Assistant Professor) at the University of Bristol, working in the area of hardware security and AI security. I previously held postdoctoral positions in leading security groups in Europe. I was a postdoctoral researcher in the System Security Lab at TU Darmstadt, Germany, working with Prof. Dr.-Ing. Ahmad-Reza Sadeghi. Before that, I was a postdoctoral research fellow at Radboud University, led by Prof. Dr. Joan Daemen and Prof. Dr. Dr. Stjepan Picek. I obtained my Ph.D. from TU Delft, the Netherlands, in 2023, under the supervision of Prof. Dr. ir. Inald Lagendijk and Prof. Dr. Dr. Stjepan Picek.

My research focuses on AI-augmented physical and micro-architectural hardware security, as well as AI security. I have published in top-tier security and cryptography venues, including USENIX Security, NDSS, ASIACRYPT, TCHES, and TDSC, and received the 2023 Informatics Best PhD Dissertation Award. Several of my works have been referenced in AIS 46 guidance by the German Federal Office for Information Security (BSI), and I have contributed as a main or co-applicant to several EU- and industry-funded projects.

Alongside my academic research, I worked as a Principal Security Evaluator at SGS Brightsight, the Netherlands (2017–2024). In this role, I led or was involved in several CC EAL5+ security evaluations from globally leading IC designers, focusing on their hardware and software implementation security. Additionally, I led R&D initiatives and collaborated with universities worldwide on research and innovation.
