Internship Program


Many of us have been lucky enough to be mentored by someone in our lives—and CST believes it’s our responsibility to provide opportunities for hands-on internships to future scientists.

One of our most successful community initiatives is our Summer Internship Program, which runs from late May through mid-August. By employing and training students from our surrounding communities and colleges, CST is able to provide summer interns with a positive hands-on experience at the bench, where they can help perform experiments and learn valuable technical skills from our knowledgeable scientists.

Student interns are paired with CST mentors in multiple areas of scientific discovery and business including our R&D, Production, Marketing, and Information Technology departments. Many of the student interns are invited to continue their internship for consecutive years. After completing their degrees, several interns have returned as full-time employees.

Intership 5

A summer intern and her proud mentor at the annual Internship Poster Session held to display interns’ projects and help them earn valuable experience presenting their work.

In 2018-19, we hosted 80 interns with a program investment of $375 K. Six of the interns have become full-time CST employees since finishing their degrees. The internship program was paused for 2020-21 for COVID safety, but returned in 2022 hosting 30 interns.

  • An average of 40 students are hired for paid internships at CST each year.
  • All interns are assigned a hands-on project which they must complete by the end of the summer, and they present their results to CST employees at a poster day.
  • Top-performing interns have been awarded $2,000 scholarships, and recognized at our Town Hall company meetings.
