Genomics Experience for Master R53s Students (GEMS) is a 12-week full-time, on-campus program designed for master's level quantitative scientists. It aims to provide an immersive experience for students to engage in real-world team science projects, applying and translating their quantitative skills into meaningful scientific contributions in cancer medicine, with a specific focus on cancer genomics and precision oncology. The program allows students to fully engage with mentors and a multidisciplinary research team on cutting-edge projects, preparing them for genomics-oriented data science careers. Each fellow benefits from a dual-mentorship model (one quantitative/computational mentor and one scientific mentor) to foster an interdisciplinary and immersive training environment. Trainees need to demonstrate a strong interest in learning cancer genomics, though prior experience in this area is not required. The GEMS program is supported by the National Cancer Institute (R25-CA272282) and the MSK Society.
