Hi, I'm Xianglu — most call me TJ.
I explore how culture shapes agency — and how AI might illuminate rather than obscure the paths we choose.

Focus
How AI can deliver culturally wise interventions — and building the theory to support it.
Methods: from NLP modeling of global narratives to field studies. Scope: East, West, Global South.
I care about fairness, and helping people find their agency.
My research question: how can AI deliver culturally wise interventions? I'm building the theory of culturally wise interventions — spanning from NLP modeling of global narratives to field studies across East, West, and the Global South. I care about fairness, and helping people find their agency.
