Roman Dolgopolyi

I am a PhD student in Computer Science at Northeastern University, advised by Professor Upol Ehsan. My research focuses on Human-Centered AI, making sure that the way people and AI systems interact is both responsible and effective.

Before starting my PhD, I held an R&D position at GRNET under the Hellenic Ministry of Digital Governance, where I trained and fine-tuned foundation models on supercomputers such as MeluXina and ARIS. I also worked as a researcher at the AI Lab and the SWIFT Lab at the American College of Greece, focusing on integrating Explainable AI into medical and wireless communication domains. I earned my bachelor’s degree in Cybersecurity with First-Class Honours from the Open University, UK, and the American College of Greece.

Outside the lab, I enjoy developing new AI applications and have won various AI hackathons, including ones organized by OpenAI and Hugging Face.
