Undergraduate research experiences enculturate students into the research community by providing support networks to explore advanced professional opportunities. However, transfer students are at a considerable disadvantage for pursuing these opportunities due to the time constraints imposed by institutional structures. Here, we report a case study of a novel summer bridge program to prepare incoming transfer students for research experiences in biological sciences. During the summer, participants committed to full-time program activities, including hands-on training with laboratory techniques through research projects and designing and executing an independent project. Pre- and post-program surveys were administered, and participants reported substantial gains in research self-efficacy and knowledge of scientific career pathways. Participants also reported strong learning and social support in the program. After the program, 30 out of 32 participants secured positions in faculty laboratories, with most continuing on to positions in industry, graduate programs, or medical and health professions. In a post-program interview, participants reported many benefits from the program, such as mentorship from faculty, developing transferable skills and research interests, and an easier transition from community college to university. While descriptive, this summer bridge program could inform future design-based research and implementations in different institutional contexts.
