Hello! I am a visiting scholar at Seoul National University advised by Prof. Youngjae Yu . I recently completed Master in Computer Science and Engineering at The Ohio State University under Prof. Sachin Kumar . Before that, I completed my undergraduate at University of Texas at Austin.

My research focuses on building safe and socially aware language technologies. I explore how LLMs can engage safely with users of all backgrounds and how well they grasp human behavior in social contexts. My goal is for language models to serve people equally well, regardless of their expertise or familiarity with AI.

I have previously worked as a Software Quality Assurance Engineer intern at Avathon (previously SparkCognition) and VPlusLab.
