이예림 · Undergraduate, Ajou University

I am an undergraduate in Software and Computer Engineering at Ajou University and an AI Research Intern at INEEJI, where I build agents that read weather charts for forecasters.

My primary interest lies in trustworthy AI agents and systems for finance and high-stakes domains, including explainable AML and compliance infrastructure for blockchain. I aim to build reliable, transparent, and verifiable AI solutions for critical real-world applications.
