Post-baccalaureate Research Education Program (PREP)
Our Post-Baccalaureate Research Education Program (PREP) accepts applications from mid-November through mid-March each year. Program activities start in July. Hopkins PREP is funded through several sources, including the Vivien Thomas Scholars Initiative at Johns Hopkins and individual research mentors.
Who Should Apply:
- US Citizens or Permanent Residents with a keen interest in entering a PhD program.
- College seniors or recent graduates with a bachelor’s degree in biomedical science— including but not limited to biochemistry, bioinformatics, biology, biomedical engineering, biophysics, chemistry, cell biology, computational sciences, genetics, mathematics, microbiology, molecular biology, neuroscience, tissue engineering, virology and related fields.
- All eligible students interested in careers in public health, science, and medicine are encouraged to apply
We consider a variety of factors that demonstrate scientific potential and motivation for PhD careers. Applicants should have strong grades in science and math (GPA 3.3 or better) or a strong upward trajectory in science/math grades. Exceptions may be made for students with research experience.
In accordance with applicable law, race, ethnicity, gender, and other legally protected characteristics will not be considered in the selection process.
