Jon, aka 백승찬 (Baik Seung Chan), is a KAD currently living in the Detroit area.

He is an award-winning professor of mathematics with over 17 years of teaching and tutoring experience. He values equity and believes that learning should be equitable for everyone. He is passionate about what he does, and his goal is to make sure every student knows that he cares about them.

On a tour of Seoul in 2018 during his first trip back to Korea since being adopted, one of his friends gave him the nickname Prof. Seung Chan. The name has stuck with him as a reminder that he should be proud of who he is—past and present. He now uses the name Prof. Seung Chan on his weekly podcast with his friend Nick Ha.

His hobbies include going to Detroit Pistons games, eating tacos, and drinking the occasional bottle of soju. One of his goals is to eventually visit every MLB Stadium and go to Paris when he retires.
