Hi there! I’m a Research Resident at the Social Computing Group, Microsoft Research Asia. I previously graduated from the University of Chicago (2025) with a B.S. in Computer Science and a B.A. (Honors) in Cognitive Science.

I’m broadly interested in understanding intelligence. My research sits at the intersection of LLMs and cognitive science, with a focus on mechanistic interpretability - to uncover, explain, and control the interesting and surprising behaviors that emerge in AI systems. Ultimately, I hope this line of work helps us reflect more deeply on what it means to learn, think, and be human.

During my undergraduate years, I was fortunate to collaborate with Prof. Xuechunzi Bai, Prof. Chengzhi Mao, Dr. Andrew Lee, and Dr. Valentin Hofmann.

I’m also a competition math specialist, indie music enthusiast, magazine writer, and startup builder. You can learn more about my life in this tab. For my blogs, you can visit the blog tab.
