Jieen Chen, PhD
AI Software Engineer
PhD, University of Tübingen · Academic Director, Kepha Institute (CIU)
Multimodal systems, knowledge graphs and AI security.
Jieen Chen develops AI software at Gargantua, working with large language models, multimodal models, and knowledge graphs. His background combines machine learning, computational imaging, and cybersecurity.
Jieen earned his PhD in computer science from the University of Tübingen, where his doctoral research explored machine-learning approaches to designing computational photography systems. He previously completed a master’s degree in photonics. This grounding in imaging and computation complements his work on systems that combine visual information with other forms of knowledge.
He also serves as academic director and lecturer for the cybersecurity master’s programme at Kepha Institute of Columbia International University. His teaching covers computer networks and programming, alongside research at the intersection of AI and cybersecurity.
