Students in science lab

The Science, Technology and International Affairs (STIA) major applies cutting-edge science to the world’s most pressing political, social and ethical issues. Using interdisciplinary methods, students will explore the technological and scientific issues at the heart of today’s international affairs. The major is run by the STIA Program, which drives innovative research and organizes high-profile events at the nexus of science, technology and international affairs.

The STIA curriculum complements the SFS foundation in international affairs with a foundation in science. STIA majors combine these subject areas to confront emerging global challenges, such as climate change, cybersecurity and global health. Students will:

  • Learn alongside their STIA cohort in the major’s foundational course
  • Engage with scientific theory and practice through a laboratory-based science sequence
  • Develop multidisciplinary expertise in one of four concentrations
  • Incorporate scientific knowledge and methods into their study of international affairs

Foundational Curriculum

STIA majors complete an introductory course, Science and Technology in the Global Arena, about the intersecting subjects at the heart of their field, and develop a degree of expertise in at least one field of science, including biology, chemistry, physics or computer science. Research and analytic methods also form an important part of a STIA education.

Specialized Concentrations

Students can pursue any of four concentrations that explore different intersections of science, technology and global affairs: Energy and Environment; Business, Growth and Development; Biotechnology and Global Health; and Science, Technology and Security. For students interested in pursuing a career in medicine or engineering, the STIA concentrations offer a global perspective on these future courses of study. No matter what career path you choose, the STIA major will prepare you for a role that uses cutting-edge science to explore global challenges.

Scientific Communication with STIA

Clear and concise communication of scientific knowledge is essential in both scientific inquiry and international affairs. In the STIA major, students learn how to ask incisive questions to guide their research, as well as how to analyze relevant data, evaluate arguments and present their findings. In addition to the introductory course and STIA electives, students also enroll in either a semester-long Senior Seminar course or the year-long STIA Honors Thesis Seminar sequence to sharpen their research, writing, discussion and presentation skills. The Honors Thesis course enables students to produce a robust piece of original work that they present to faculty and peers.

Graduates will be able to share their scientific knowledge in accessible and engaging ways and translate their expertise into effective decision-making.
