Research Associate

Arielle Mattes serves as a Research Associate at The Critical Mass. Before joining TCM, Arielle worked as a Technical Graduate Intern with the International Safeguards and Engagements teams at Sandia National Laboratories. At Sandia, she conducted research for a Cognitive Informed Safeguards Booklet for the International Atomic Energy Agency safeguards practitioners (published in ESCARDA Bulletin 61). She spearheaded two project deliverables for NNSA’s NA 81 Office of Counterterrorism: a facilitator and participant workbook for a virtual CBRNE Weapons of Mass Destruction Commodities Identification Training course. At Sandia, Arielle closely collaborated with Sandia’s colleagues at CIRMF in Gabon by translating documents and monthly meeting notes from French to English. Prior to joining Sandia, Arielle worked with the Council on International Relations where she assisted with communications for the annual 2019 Journalism Under Fire conference in Santa Fe, New Mexico. She interviewed Ambassador Chris Hill in front of a 500+ audience for the Council’s annual Gala. 

 

Arielle is a recent graduate from the University of New Mexico’s Global and National Security Policy Institute. She graduated in December 2020 with her Master of Science, and in May 2019 with her bachelor’s degree in Psychology. She holds professional certificates in Policy and Technical Fundamentals of International Nuclear Safeguards (Texas A&M), Nonproliferation and International Safeguards (PNNL), and National Security and Strategic Analysis (UNM).  

 

Growing up in a multi-ethnic home in New Mexico, she keeps an open mind to different cultures and their perspectives. She is multi-lingual in French and English, and holds dual citizenship with Belgium. Her travels in 14 different countries have contributed to her global mindset and continues to inspire her to follow international affairs.  

 

In her spare time, Arielle enjoys doing yoga, rock climbing, and making art.
