  • Integrated Data-Driven Discovery in Earth and Astrophysical Sciences (IDEAS) 
    IDEAS is a multi-faceted program designed for masters and PhD students in a variety of departments; students can participate at a range of levels. At its core, the program offers a range of coursework in data science. As part of the program, students can also participate in summer school activities focused on data visualizations and computer programming, engage in science communication workshops, participate in the development of a citizen science project related to their research focus, and earn an internship opportunity. More details on the programs are available on our Traineeship page. Students who wish to take only the core coursework will be able to receive a certificate granted by The Graduate School at Northwestern University. 
  • TGS Integrated Data Science Certificate
    Northwestern’s Graduate School offers certificates to help connect doctoral students across various departments and programs. Earning a certificate not only formally recognizes a student’s focus on and achievement in a particular topic area, but helps form a cohort of students and faculty interested in particular interdisciplinary areas. Certificates typically require five course for completion; the certificate will appear on your transcript.
  • Northwestern Institute on Complex Systems (NICO)
    The Northwestern Institute on Complex Systems was founded in 2004 with the goals of uncovering fundamental principles governing complex systems in science, technology, and human behavior and applying these principles to solve societally relevant problems through the analysis, design, and control of complex systems. 
    • Graduate students and undergraduate students interested in conducting research and being matched with faculty should enter information on their programming and data science skills, research interests, and time availability here.
