Abstract

Undergraduate research experiences (UREs) are widely promoted to broaden participation in science, technology, engineering, and mathematics (STEM), yet the amount of sustained research engagement needed to support entry into biomedical research careers remains unclear. This study examined how the duration of URE participation (dosage) and participation in summer undergraduate research experiences (SUREs) independently relate to post-graduation educational and career trajectories among students historically underrepresented in scientific research careers. Using longitudinal data from 322 BUILD PODER participants, we examined post-graduation outcomes from 2017 to 2025. Educational and career trajectories were classified as biomedical research, biomedical non-research, non-biomedical STEM, or non-STEM, and logistic regression was used to examine associations between dosage (1, 2, or 3 years) and SURE participation with biomedical research trajectories. Compared with two years of dosage, one year was associated with significantly lower odds of entering biomedical research trajectories, whereas three years did not confer additional benefit. SURE participation predicted entry into biomedical research trajectories after accounting for dosage. These findings suggest that two years of sustained URE participation may be sufficient to support entry into biomedical research trajectories, while SUREs appear to provide additional benefits, highlighting the value of sustained and diverse research opportunities for broadening participation in the biomedical research workforce.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
