Does AI Think Like Humans?

Do Humans and AI share "cognitive" patterns and can biases pass between them?

Humans and LLMs lean on the same hidden cues — who wrote a text, not just what it says. That shared habit is how bias travels between the two sides.

How to Align AI with Human Signals?

Which human signals should enter a model — and which should be kept out?

Human data holds both expertise and bias. I align AI to keep the expert strategy, filter the bias, and adapt to the user.

Adaptive AI for Cognitive Augmentation

Can AI sense your trust and effort in real time — and adapt to truly support you?

AI senses human cognitive states from eye and body signals, then builds a closed-loop adaptive system for cognitive augmentation.

Together they form one bidirectional loop — understand the shared patterns, align AI with the right human signals, and augment the human in return — toward collaboration you can trust when it matters most: calibrated trust, appropriate reliance, and sharper decisions.
