Meet the Student Officers

Association of Southeast Asian Nations Committee

Greetings! My name is Chris Kalogeropoulos, I am 19 years old, and I am serving as the President of the Association of Southeast Asian Nations Committee in the 5th ATSMUN conference. This is my second time chairing a committee in MUN, my first having been the Security Council of the 3rd ATSMUN conference. It may sound cliché, but participating in MUN has been life-changing for me. Through it, I have found my voice and built up the courage to speak my mind in my everyday life, and form opinions on topics that concern us all, and most importantly, help find solutions to them.

P.S.: Rainbow Alliance, REPRESENT!

My name is Alexandra Kavantouri. At 15 years of age and after 7 MUN conferences in 2,5 years, I have become conscious of current world affairs and corruption in its many forms, be that governance, pollution, human trafficking, threats to peace. I firmly believe we can all make a difference through constant learning and engagement. . I have thus gradually formed my preference in field of study and career forward.

I am a pre-IB student at Moraitis and in addition to a challenging debate I enjoy exercising in crossfit, vintage (fashion, music and movies), French literature, and law series.

My name is Ilia Papastamati, I am 19 years old and I’m currently studying law in the National and Kapodistrian University of Athens. I started my MUN journey back in 2014 but even though I have participated in various conferences, both high school and university level, it is my first time as a Student Officer and I could not be more exited for this year’s ATSMUN. Apart from conferences I love dancing, acting, reading good books and watching movies and series. In three words I would describe myself as determined, perfectionist and hard working.

Disarmament and International Security Committee

Hi! My name is Natalie Kostara and I’m currently studying law at the Aristotle University of Thessaloniki in Greece. In the following years I am planning to move abroad and conduct my post graduate degree in international relations and politics or economics.

I was first introduced in the MUN community in middle school and since then I have participated in multiple conferences both as a delegate and as a student officer.

For a long time I have been trying to raise awareness and sensitize the public regarding humanitarian and environmental issues with a focus on women’s and children’s rights and plastic pollution. Apart from MUN conferences I have a passion for art history, traveling and 90s sitcoms.

My co-chairs and I really look forward to meeting you all and we promise you that we will work tirelessly in order to provide you the chance to conduct fruitful and productive debates and create some great memories!

My MUN journey started in the first grade of high school and since then is something I truly love. The fact that I was able to take the role of a delegate, propose solutions, debate upon them with peers, exchange different views and opinions something I take pleasure in doing. Moreover, I truly enjoy the role of the chair, from the initial stage of compiling study guides and attending workshops, to the actual coordination of the debate and lobbying process. Lastly, by the time the conference begins it will be my fifth fourth time acting as a chair in an MUN conference.

International Labour Organization

Hey everyone! I am Marina Kontalexi and I will be serving as the President of the International Labour Organization in this year’s ATSMUN. This being my 4th time attending the ATSMUN I cannot describe how happy I am for being here to feel the conference changing and growing through the years. My relationship with MUN and debate began at school but I am not willing to let go. It feels like it is my duty to introduce new people to this world, that makes you feel so small in such a great way. It makes you feel that you are part of a bigger picture, that your future depends on matters much greater than those you keep getting upset about, matters that need you to act, to help, to cooperate. It makes you feel alive.

In this year’s ATSMUN I am more than enlightened to serve as the Deputy Committee Director at the International Labor Organization. In fact, ATSMUN was the first MUN conference that I have ever taken part, 3 years ago. I will never forget that conference, as it gave me the opportunity to become part of a worldwide community of amazing people and taught me that every problem can be tangled through heated and alongside fruitful debate! Apart from taking part in various conferences, I also take great pleasure in depicting reality through my photography lenses. I really cannot wait to work with every single one of you at this year’s ATSMUN!
