Shakyani Jayasiriwardene

PhD Student

I am a PhD researcher exploring how the personality traits of artificial intelligence agents shape human perceptions and behaviour. My work sits at the intersection of human-AI interaction, affective computing, and emerging technologies, with a focus on designing more intuitive, trustworthy, and human-centered AI systems.
