M. Bilgehan Ertan

I am Murat Bilgehan Ertan, a researcher at the intersection of security, privacy, and machine learning, currently pursuing my PhD at CWI (Centrum Wiskunde & Informatica) in Amsterdam under the supervision of Prof. Marten van Dijk.

I hold a BSc in Computer Science and Engineering from Sabancı University, Türkiye, and an MSc in Computer Security (cum laude) from Vrije Universiteit Amsterdam. Beyond my academic research, I have professional experience as a Security Researcher and Developer at PRODAFT.

My research focuses on building secure and privacy-preserving learning systems, combining theoretical analysis with practical engineering. I study how information leaks and adversarial behavior arise in modern AI, developing formal frameworks based on Differential Privacy, f-DP, and PAC privacy to understand and bound these effects. In parallel, I work on adversarial and membership inference attacks on large language models to evaluate and strengthen their real-world resilience.

I’m broadly interested in how we can make machine learning systems secure, private, and reliable without losing their practical value.
