I am an AI policy researcher at OECD.AI, focused on informing policy frameworks and technical designs for the safe and responsible deployment of AI. Outside of work, I am particularly interested in the governability of multi-agent AI systems.

Prior to joining the OECD, I was advised by Dylan Hadfield-Menell, Elsa Olivetti, Emőke-Ágnes Horvát, and Juho Kim. Working alongside experts in technical AI safety, supply chain systems, network science, and human-computer interaction, I found myself navigating an incredibly dynamic research landscape. While these experiences occasionally brought moments of existential crisis as a researcher, they ultimately strengthened my adaptability and the versatility needed to tackle real-world challenges of governing advanced AI systems and fostering international cooperation. Looking back, it feels like everything happened for a reason—or at least, we can choose to see it that way!

In my spare time, I like to take a stroll, play with oil pastels, and appreciate others’ creative and artistic talents – here’s my (current!) favorite [playlist | webtoon | art | recipe].
