Research Bootcamp

In August 2021, ROCS conducted our 3rd annual research bootcamp with three virtual sessions, designed for new researchers and trainees. The series provides an overview of key phases of research, didactic content including best practices, and opportunities for interactive engagement of material. The presenters also shared lessons learned and available resources across campus.
