Vassilios (Billy) Exarhakos

I'm a PhD student in the Software Technology Lab at McGill University, where I am advised by Professor Jin Guo. I am a CS researcher focusing on human-centered AI (HCAI). I design and study interactive systems that put human needs, values, and workflows at the center of AI. My interests include making AI more transparent, trustworthy, and supportive across a range of creative, analytical, and collaborative activities. As models become more capable, the challenge shifts from generation to interaction: helping users understand, trust, and steer AI outputs effectively.

Research themes

Human-AI collaboration — designing AI systems that augment human reasoning, creativity, and control
Interaction transparency — making AI systems' behavior more understandable and predictable
Controllability — giving users meaningful ways to steer, refine, and interpret AI outputs
Versioning and provenance — tracking and revisiting the evolution of human-AI co-created artifacts
