XV edition

Jonas Simorangkir

Secretary General

Jonas Simorangkir is a biology student with a personal interest in ecology, biodiversity and zoology at the University of Bonn, Germany. Born in Indonesia and growing up in the Philippines, he discovered MUNs in his high school days. Since then, he has taken part in various Asian and European conferences in both online and offline formats, “infected” with what one would call the MUN “virus” and falling in love especially with the workings of MUN crisis and press works. Jonas considers his proudest MUN moments (as of yet, since MUNUSAL 2023 is yet to come around!) to be the successful organization of Global Goals Model United Nations 2021 as Secretary-General,  BIMUN/SINUB 2020 as the Association’s Vice President and KULMUN 2022 as Deputy Secretary-General, the latter two being MUNUSAL’s beloved partner conferences. In MUNUSAL 2023, he is hoping to close the MUN chapter in his life with an amazing conference among friends both old and new, and of course fun and (dare I say?) fruitful debates.


Other than MUNing, he is a big fan of everything basketball (be it broadcasted games, live-in-person games, pickup games, video games, fantasy leagues), outdoor activities (after all, he is the son of two foresters), playing the piano (Beethoven!) and simply trying out as many new things as possible (you miss 100% of shots you don’t take).


Jonas is extremely excited to welcome you along with Julian in Salamanca next April at what will surely be a fantastic conference!

Julian Hurtubia Neitzel

Deputy Secretary General

Julian is a mechanical engineering student with a specialization in applied material science at the Karlsruhe Institute of Technology. He was born to a German Mother and a Chilean Father in the heart of Rome, with such international constellations becoming a constant in his youth due to his mother’s work at the UN. At the age of eight, he left the eternal city with his family to move to Yemen, which he later had to leave due to the deteriorating situation in the country. He then moved first to Ethiopia and later the Philippines, where he both had his first encounters with MUNing and met Jonas, with whom he quickly became great friends.

After finishing his Highschool education in Manila, Julian moved to Karlsruhe in Germany to begin his engineering studies. There, he joined MUNIKA, the local MUN association, and his initial interest in MUNing became a passion. Feeling right at home in the international setting, he quickly became the organization’s Treasurer and Board Member for 3 Semesters. Additionally, he co-organized MUNIKA’s yearly conference as a Member of the General Secretariat and has chaired in several other MUN Conferences, most recently in KULMUN in Leuven.

Currently holding a bachelor’s in mechanical engineering, Julian is currently in the process of doing his master’s in the same subject. He is interested in anything from science and technology to history and politics. In his free time, he enjoys coffee, reading, jogging, and obsessively following current world events.

But most importantly, now Julian is looking forward to seeing all of you at MUNUSAL next April!

José Grande Santalla

UNGA Chair

Jose tiene 23 años y está orgulloso de ser uno de los dos chairs del Comité en español. Su primer MUN fue Munusal 2019, en este mismo Comité; desde aquella no ha parado de descubrir el mundo de los MUN y conocer gente increíble.

Es de Galicia, pero este año está viviendo en Bruselas con una beca. Anteriormente estudió Periodismo y un máster de Estudios Internacionales en la Universidade de Santiago de Compostela. En su tiempo libre podéis encontrarlo normalmente viendo/jugando/hablando de fútbol (seguidor del Barcelona y el Racing de Ferrol), escuchando todo tipo de música (desde protopunk a cumbia de Santa Fe), leyendo, paseando o simplemente pasando un buen rato con amigos.

En sus palabras, "si es tu primera vez en Salamanca, no lo olvidarás. Si es tu primera experiencia en un MUN, tampoco. Si ya has hecho ambas, sabes de lo que hablo. ¡Nos vemos pronto!".

Sebastián Cuevas

UNGA Chair

Sebastián Cuevas nació en Venezuela hace 21 años, debido a la situación de su país tuvo que emigrar a Panamá donde pasó casi toda su juventud y donde empezó su vida en el mundo del MUN, luego de 9 años, tuvo que mudarse a Perú para finalizar sus bachillerato y finalmente a España para estudiar en la universidad. Actualmente estudia Ciencias Políticas en la Universidad de Salamanca. Para Sebastián, haberse mudado entre estos países le ha permitido tener experiencias culturales diferentes y también a pensar de una manera un poco más abierta. Desde pequeño siempre ha sentido impotencia por los problemas que pasan en su país y en el mundo sin poder hacer nada, esta impotencia le ha servido como motor y motivación para poder llegar en algún momento a ayudar en una escala local o global a las personas que lo necesitan.  Debido a esto y a otros motivos a Sebastián le empezó a interesar el mundo del MUN, donde ya lleva más de 7 años siendo delegado y mesa directiva, ya que considera que además de ser muy divertidos, también funcionan como una formación profesional para el futuro. 

Está muy feliz poder ser parte de MUNUSAL y no puede esperar por verlos en abril.
