The Disarmament and International Security Committee (DISEC) is the first committee at the General Assembly of the United Nations. The committee was formed in 1945 when the Charter of the United Nations came into force, and has since been assigned to the role of maintaining international peace and security.

Today, DISEC is an enormously influential committee of the UN, as it has been the driving force of international agreements relating to various issues such as the small arms trade, and the use of weapons of mass destruction. These feats of international cooperation can only be completed in such an assembly, which welcomes 193 member state delegates into an annual forum for discussion on pressing, world security issues.

DISEC offers the traditional Model United Nations experience for delegates of all experience levels. Position papers are recommended for this committee, but are mandatory for delegates to be considered for awards. Please read about CAHSMUN’s Position Paper policy, which can be found under the list of committees on the “Committees” page.

Joyce Chen | Director

Joyce is a junior at Little Flower Academy and is elated to be serving as the Director of the Disarmament and International Security Committee at CAHSMUN 2020. It is with immeasurable gratitude that she credits Model UN for inciting her interest in international relations; since then, she has learned to incorporate perspectives independent of her own into her worldview, to remain cognizant of issues that exist beyond her own borders, and to instill this knowledge in generations of leaders to come. Outside the committee room, Joyce revels in listening to true crime podcasts, consuming alarming amounts of iced coffee, and getting pitiful amounts of sleep. Most of all, she excitedly awaits the nuanced and thought-provoking debate that will take place at CAHSMUN 2020!


Serena Chen | Chair

Currently in her Grade 12 year at Crofton House School, Serena is ecstatic to be serving as the chair of DISEC this year at CAHSMUN. Ever since she was peer pressured into attending her first conference in 2016, Serena has attended multiple conferences— and has been drawn into the world of Model UN, with its rapid debate and intricate resolutions. Outside of MUN and school, Serena spends the majority of her time on the basketball court or in orchestra rehearsals with her cello. Her free time is spent scouring Facebook and Instagram for new places to visit in Vancouver, and rewatching episodes of Lucifer on Netflix while consuming copious amounts of coffee (even though it does nothing to help her sleep deprivation). She is very excited to meet all delegates at CAHSMUN 2020 and hopes that it will be a memorable experience for all!
