Olatunji Iyiola Emmanuel (李白)

Postdoctoral Researcher



Emmanuel works as a postdoctoral researcher at CISPA with Adam Dziedzic and Franziska Boenisch on the privacy of large language models (LLMs) in the SprintML lab. Emmanuel is currently completing his PhD at Leibniz Universität Hannover (LUH) under the supervision of Prof. Wolfgang Nejdl and Asst. Prof. Megha Khosla, focusing on the privacy of graph neural networks (GNNs). He is deeply passionate about the privacy of machine learning models and excels in identifying vulnerabilities in machine learning models by lauching attacks and developing defenses, with a particular focus on the strategic implementation of differential privacy techniques to foster a more secure, responsible and ethical AI. He was a researcher in the L3S Research Center and Leibniz AI lab. He was a visiting researcher in the Multimedia Computing (MMC) Group at TU Delft.
