Joon Baek has been involved with the Columbia College Student Council as the International Student Representative and later, the Student Body President. He has been an advocate and leader for his international student peers on and off the Columbia campus. With new rules forbidding international students from entering the US in the shift to virtual classes, he led an initiative to protest against the rule, eventually being selected by the New York State Attorney General to speak at a press conference as an international student leader. Through his positions and involvement on campus, he has dedicated his time to advocate for a more inclusive and supportive environment for international students.
