Ian Toyota
Director-General

He never heard about Model United Nations until post high school. In his case, this was when he joined Harvard University and found out about the International Relations Council. Over the past 3 years of being a member, he has gained a lot of experience, both substantively and executively. He served as an assistant director twice, and a director twice, and he is very excited to be coming back to Africa as Director General, having been a committee director at this conference's very first iteration in March 2024.

He can't wait to meet everyone in March!
