Polina got the "MUN virus" about 2 years ago when she participated at UNISCA conference as a Chairperson at the Security Council. GIMUN and TEIMUN quickly followed the same year. Back in 2007 she considered the idea for organizing the first Model United Nations conference in Bulgaria as one of the most exciting initiatives she had ever undertaken. It did not take long to Paola, Dimiter and her to start real preparation for their common goal. Thanks to their entrepreneurial pro-activeness to create this exciting member of the MUN's family now in 2009 the 2-nd edition is under way.

Polina's friends say they like working with her because of the constant positive energy she has and her open-minded personality that helps innovation to prevail.

Mr. Andrey Stoichev

Fundraising specialist of the SOFIMUN Foundation



His life revolves around three things: politics, private enterprising and the preservation of Bulgaria’s cultural heritage.

Since 2005 he is a campaign manager, well it’s plain to see what it’s about, managing election campaigns. Sometimes and especially after the fifth one in a row he thinks that he is not managing it, but it’s the other way around. As soon as the elections are over, he and his colleagues from the department of political sciences at the New Bulgarian University, bang there heads at the question "Why people keep making the wrong choices time and time again?”. He and his friends are convinced that there is a world conspiracy aimed at rendering logic and reason worthless and to turn the conscious choice, which the voting is, into unconscious one.

From December 2006 he has gained interest in another area - the preservation and promotion of Bulgaria’s culture and heritage. So he and some friends started an NGO called National Union "Treasure the Bulgarian Heritage".

As far as private enterprising is concerned, in May 2007 he started his own business. Since then he says: "Moneymaking is a wonderful thing!”

You can say that his life has run at a very slow pace in the last four years, didn’t it? ;-)


Ms. Victoire Rio

Regional Cooperation (Western Europe) of the SOFIMUN Foundation



Born in Paris, Victoire got the traveling bug early on and left the city of love to discover the world. After a year in high school in the United States, she never stopped moving. She went to study in England, then again in the United States, then England, with a lot of travels in between. Difficult to keep track! Holding a bachelor in politics and international relations, and having written her dissertation on Bosnia Herzegovina, she decided to move to BiH to discover a place she had spent so many late hours reading about.

Ms. Irina Botea

Regional Cooperation (Balkans) of the SOFIMUN Foundation



Born and raised in Bucharest, Romania, Irina likes to think about herself as being a very lucky and some would also add courageous person. Taking life as it comes and accepting all its challenges is the way she got to live a pretty busy life for 22 years. Being a students representative three years in a row, Member of her Faculty’s Council and editor-in-chief for the department’s magazine, Irina tried to be an active member of her community and set an example for the others. After graduating in International Relations and European Studies at the University of Bucharest, Irina is currently finishing her masters in European Studies at the Catholic University of Leuven, in Belgium.

In 2008 she ended up, by chance, at her first Model UN where she got contaminated almost immediately with the so called MUN virus. Besides the intense debates, the main triggers for the virus were the wonderful people she met there and which now she feels honored to call them “friends”.

Several conferences later she thought it would be appropriate to give something back to the MUN community since she received so much from it. Spreading the MUN values around the world may sound impossible but with a bit of perseverance, determination and a wonderful team besides her, she believes we can achieve anything.
