Hi Fiepre, given you interest in Chemisty and International Relations, have you considered exploring careers at international organizations? For example, within the United Nations system, there's UNESCO (United Nations Educational, Scientific, and Cultural Organization)
One place to start is by checking out UNESCO job opportunities, fellowships. and internships to learn about the types of roles that might be available and potentially connect with individuals who are currently at UNESCO to tell you about their academic and professional journeys.
The American Chemical Society also provides some helpful resources on career options in the chemical sciences, some of which are related to working in the government, nonprofit, and academic spaces that might combine your interest in international relations.
