The ASPIRE Fellows participate in the design, development, and construction of world-leading particle accelerators presently under construction at Fermilab. The ASPIRE fellowship provides immersive learning experiences, at Fermilab, to undergraduate and graduate (masters) engineering students, who are historically and contemporarily underrepresented in accelerator engineering fields, including Black, LatinX, and Indigenous identities, and women. Under the guidance of an assigned mentor, participants realize professional growth and development by acquiring in-demand engineering skills and establishing professional networks within the U.S., accelerator science and technology community. The Fellowship lasts 15-18 months and fellows are paid while in residence. Applicants must be U.S. citizen or permanent resident at time of application.
