Chairs: Tomas Alvarez Sielaff and Klaus Hoeltgebaum

Tomas Alvarez Sielaff


My name is Tomas Sielaff Alvarez, a Brazilian/German/Spanish/Argentinian 22-year-old, aspiring diplomat living in the capital of Germany. I am interests range from politics/economics to playing the violin and sometimes being a goalkeeper. My passion for MUN started during High School in Curitiba Brazil, the city where I was born and grew up in, at the International School of Curitiba, where I was fortunate enough to have MUN as an elective class for 2 years. Right now, I am at the beginning of my bachelor’s degree in History and American Studies at the Humboldt University in Berlin and can say that 5 years and 19 conferences later MUN is and will always be an addiction/passion of mine that I do not think I’ll be ever able to get rid of.

Klaus Hoeltgebaum


Hello, my name is Klaus Hoeltgebaum,  I’m a 20 years old Brazilian currently and Economics and Business Economics student in Amsterdam. I’ve always enjoyed MUN and done it since high school, and now in university I continue enjoying it as conferences are always a great place to meet people, improve debating skills and keep up with international affairs. I usually take up the role of delegation since representing a country and debating positions is so much fun, but this year I’ve decided to try out as a chair. This will be my first year as a chair and in my favourite council (best one for intense moments), and I’m looking forward to meeting you all in Utrecht!



Chairs: Francine Brownell and Natalie Gates

Francine Brownell


I am Francine Brownell, and I am studying Global Economics and Politics at the University of California, Santa Cruz in the US. I am studying abroad at the University of Geneva for spring semester, to get a better understanding of International Relations. I have been doing Model UN for a little over a year, and back in Santa Cruz I help teach a class about MUN as well as have an active role in the leadership of the club. I love it because it is the perfect way to learn about international issues while getting better at negotiating and public speaking. I am looking forward to chairing the UNHRC Committee with Natalie and visiting Utrecht, as I have never been to the Netherlands before! I hope to see y’all there!

Natalie Gates


Hi, hello! My name is Natalie Gates, an American exchange student, currently living in Paris for the year and studying at SciencesPo. I study Politics with a concentration on theory, and political history at the University of California, Santa Cruz. I am going to be a chair for the UN Human Rights Committee, and I know my co-chair from my home university! I’ve been involved with MUN now since I was eleven years old. I represented the country of Pakistan in the committee for Disarmament. Just one girl in the entire committee, and representing one of three countries not apart of the NPT, commanding respect from pubescent boys proved difficult, how I imagine the women in the US Congress must feel. But the experience taught me how to communicate, how to speak, how to humanize. And I walked away with an award, respect, but most importantly, empowered. It has been a medium for me to challenge my own opinions, to improve my understanding of the world and history, to be forced to reason with unreasonable and horrific policies, to conceive of viable solutions on a micro and macro level. In MUN one is taught the issues that invade the livelihoods of humans, and to listen, to be pragmatic, to compromise, to empathize, to see the humanity in the worst of conditions. I fell in love with MUN because it was a platform to incite political efficacy and charge individuals with a power to act caused by awareness. I am ecstatic to meet you all, have the chance to hear new voices, see new faces, learn about the countries represented, while enjoying the lovely city of Utrecht come spring. Bonne journee!


Chairs: Alina Chakh and Charlotte McNally

Charlotte McNally


I am Charlotte, a British law student studying in Utrecht on exchange from Cambridge and I am so excited to be serving as chair in NATO! My Model UN career began in 2014 at the huge high school conference, THIMUN and this academic year has seen me become a United Netherlands delegate. In November, I participated in the Human Rights Council at OxIMUN and am representing Japan in the Legal Committee at HNMUN this February. With much personal experience as a delegate, therefore, I know what is needed from a chair for constructive, intelligent and enjoyable debate to flourish. Chairing will be my next challenge and I very much look forward to sharing it with you! I am certain you will leave URUMUN with greater insight into some extremely topical international issues as well as having met a community of ambitious and fun young people.

Alina Chakh


My name is Alina and I am a 22-years old law student. It is such a pleasure to be chairing NATO at URUMUN 2018! URUMUN has a special place in my heart. As the Secretary-General from URUMUN 2016, I am very proud to see what this board has achieved so far, and I am sure that it will be a remarkable success! Therefore, I am really looking forward to chairing this event and experience URUMUN from another point of view. I just started my Master’s in Constitutional Law at the University of Amsterdam and I received my bachelor’s degree at Utrecht University. I always had a fascination for debating: in high school, I participated in a national debating competition called Op Weg Naar Het Lagerhuis. Luckily, we won the competition and our prize was a trip to the United Nations in New York and I think that’s when I first fell in love with MUN! I joined the MUN team of Urios and we went to Paris and Antwerp to participate in a MUN. I had such a wonderful time and I want to encourage everyone that is in doubt whether to join URUMUN to participate. You will definitely meet special people and have the best time in the nicest city of the Netherlands: Utrecht! I hope to see you all there and I personally cannot wait for URUMUN 2018!
