I’m a storyteller at heart—entrepreneur, scientist, and author

🚀 Entrepreneur: I'm building Wondi—an API that detects suicidal ideation and self-harm risk in adolescent AI companion conversations, backed by MIT Sandbox, MIT R2E, and Google for Startups, which is upto 70K non-dilluted fund. I also founded the "STEM Vision Scholarship", Korea’s first college-run program that provides annual financial aid and mentorship to underrepresented high school students

🔬 Scientist: My entrepreneurship is rooted in five years of research. Working with Professor John Gabrieli ,pursuing a Ph.D. in Brain and Cognitive Sciences in MIT, on the ABCD dataset of 10,000+ adolescents, our models achieved 92% AUC in predicting suicidal attempts—and convinced me the science was ready to leave the lab.

✍️ Author: I have written Korean blogs (1M+ views) for 6 years and published 5 books. 

All this journey was sparked by my journey through depression and fueled by the conviction that AI can transform mental health care, making it not only accessible but also deeply personalized
