Board XXXIII
Thomas van Loon,
President
My introduction to Model United Nations is something I will never forget. I realised I had found something that touched upon all my passions: my interest in the world, in International Relations, in exchanging ideas and cultures, and my commitment to diplomacy and dialogue. As a delegate of the Foundation, I noticed the impact MUN can have in someone’s life: it helps people overcome their fears and insecurities and it builds a crucial skills set.
Having seen and experienced the power of the Leiden MUN Foundation, and the importance of having great inspiring mentors and Board Members throughout this process, it is my distinct honour to serve the Foundation as President for IEUMUN 2025. I am excited to give others the opportunities I was given and hope to motivate, inspire, and bring out the best in our new delegates.
Ethan Schwartz,
Vice President
What the foundation emphasizes most in those who are a part of it is growth. Since walking in to my first skills lab a year ago, I have grown tremendously as a public speaker, professional, and person
As I look to the very MUN conference with which I began, now as a board member instead of a delegate, I feel an immense pride and thankfulness in what the foundation has given me, and what I have been able to contribute to it. As vice president for this IEUMUN 2025 preparatory track, I hope to witness a smooth experience for our delegates and the board. With experience under my belt from our SIMUN prep track this past spring, I hope to be integral in my new leadership role as a committed trainer for our delegates and a reliable logistician on the less-glamorous side of my duties.
Juan Escudero,
Head Delegate Trainer
Participating in the IEUMUN 2025 Prep Track will mark my third and final journey with Leiden MUN. Over the last two years, I have not only grown as a delegate and a board member, but also honed skills that have shaped my confidence and ambitions. Now, I want to give back all that I have learned, both from my own experiences and from the invaluable guidance of my two previous Head Delegate Trainers.
I remain deeply committed to the Foundation’s mission of personal development, and I am eager to embrace this new role. My goal is to ensure that our new delegation finds in this Prep Track the same enriching, transformative experience that I was fortunate to receive, and to walk with them as they grow into stronger, more confident versions of themselves.
Jaclin Duja,
Promotions and Acquisitions Officer
As I complete my 3rd and final Prep Track with the Board, I can only look back and feel grateful for what Leiden MUN has given me in the last year. Beyond the invaluable academic and professional experience, being part of the Foundation brought me a newfound trust in the skills I have developed as both P&A Officer and mentor and a whole lot of fond memories that have enriched my university experience. I've had the privilege to work with some incredible people, learning a great lot from the team and the community, and I am only proud to carry the name and image of the Foundation as we go forward with the IEUMUN delegation
David Auberger,
Treasurer
MUN has been eye opening for me; a whole experience parallel to university that transforms your professional abilities. My studies would never feel quite as complete without the foundation, as I firmly believe MUN is a central stepping stone to any International Relations student’s career. As my friends know well, I am always eager to recommend it to anyone I meet.
After having participated in IEUMUN 2024 and HNMUN 2025 as a delegate, I am honored to be on the board for IEUMUN 2025. Now as treasurer, I can contribute positively for a more affordable, fairer and responsible foundation. I can sincerely say that I have found my voice in the community, by sharing with likeminded individuals a common passion for self improvement, diligence and determination, all under the umbrella of International Relations.
Sixte Foucque,
Delegate Trainer
"The greatest glory in living lies not in never falling, but in rising every time we fall." This quote by Nelson Mandela is the ideal synthesis for everything that the Leiden Model United Nations Foundation stands for. My MUN journey started over 3 years ago. Every speech was a learning opportunity, every moderated caucus, a trove of teachings. As I join the Board XXXIII, I am honoured and humbled to teach others, the lifetime of lessons MUN has taught me.
Julia Pozdnukhova,
Delegate Trainer
It is a great honour and responsibility for me to be a member a of the Leiden MUN Foundation Board XXXIII.
I am deeply convinced of the unique value of our delegate training program, as I have completed it twice myself, participating in various UN models. It was an incredible experience that made me stronger and gave me a lot on a personal and professional levels. As a delegate trainer, I want to share it now.
"Finding your voice" is not just words for me. It is not about the pitch of the sound and the right intonation. Most importantly, it is about gaining confidence, about the strength of conviction, about the inner fire and faith in yourself!
