Hidde Lycklama

I am a fourth-year Ph.D. student at the Privacy Preserving Systems Lab. My research focuses on the robustness and accountability of secure (collaborative) learning systems. My goal is to design systems that balance privacy and transparency through the application of cryptography such as zero-knowledge proofs and secure multi-party computation, based on a rigorous understanding of learning systems' integrity issues. I completed my M.Sc. degree at ETH Zurich in Computer Science. Before that, I graduated cum laude with honors at the Delft University of Technology with a B.Sc in Computer Science.
