Hi, My name is Junsu Kim.

I am on a journey searching for ideas and people that can make a fundamental **change to the world.

Currently my primary goal is understanding intelligence, especially thinking-the state of the art method humanity has ever had to solve a new problem. As a student researcher in Google DeepMind,  I am focusing on exploring thinking.

Furthermore, I am also interested in the anthropologic and economic consequences of intelligence.

My journey stems from **Ryu Optimization Group,** where I first dived in the field of artificial intelligence and learned how to reasearch. Before that, I enjoyed my time preparing for IMO, where I first learned how to think*.*

If you'd like to chat, I'm hosting a **30-minute Chat** every day. Feel free to connect-I love talking with new people!
