Machine Learning and Cryptanalysis

I am currently a postdoctoral researcher at Nanyang Technological University (NTU), Singapore, ranked 2nd worldwide in AI research within Thomas Peyrin’s group. My current research conducts adversarial machine learning and cryptanalysis, e.g. model stealing or new adversarial attacks.

Previously, I earned my PhD with “magna cum laude” from Heidelberg University, Germany. Link to PhD thesis.
