4 Years On Campus Bachelors Program
Harvard University’s Human Developmental and Regenerative Biology (HDRB) concentration is designed for students interested in understanding how humans develop, maintain tissues, regenerate, and age, combining modern life sciences with chemistry, physical sciences, mathematics, and laboratory research. The program particularly suits students interested in human biology, developmental biology, regenerative medicine, biomedical research, and medicine, with hands-on research integrated throughout the undergraduate experience.
Curriculum Structure
Year 1: Students establish their scientific foundation through Life Sciences 1A and 1B or the alternative Life Sciences 50A/50B sequence, alongside quantitative science and chemistry/physical-science preparation. This stage develops fundamental biological understanding while establishing the chemistry and mathematical background required for later HDRB study.
Year 2: Students move into the concentration through SCRB 10: Human Developmental and Regenerative Biology, Harvard’s gateway course, which introduces developmental biology through the developing and regenerating mammal and emphasizes experimental methodologies. Students also progress through SCRB 50 or MCB 60 for molecular biology and complete organic chemistry such as CHEM 17 and CHEM 27 or the approved equivalent sequence.
Year 3: Students deepen their understanding through 100-level Stem Cell and Regenerative Biology courses and advanced courses available through related fields such as Molecular and Cellular Biology, Organismic and Evolutionary Biology, and Human Evolutionary Biology. The concentration also includes SCRB 91R, a semester-long independent laboratory research course that provides direct experience conducting experimental research.
Year 4: Students complete advanced HDRB coursework while continuing to develop their independent research interests; students pursuing honors undertake SCRB 99A and SCRB 99B and complete a senior thesis. This final stage allows students to bring together their knowledge of human development and regeneration with substantial independent scientific investigation.
Focus areas: Human biology, developmental biology, regenerative biology, stem cell biology, molecular and cellular biology, disease mechanisms, chemistry, physical sciences, quantitative science, laboratory research, and translational applications.
Learning outcomes: Students develop a strong understanding of human biology and the biological principles underlying development and regeneration; apply biological knowledge in laboratory settings; build foundations in chemistry, physical sciences, and mathematics; conduct experimental research; and understand how fundamental biological discoveries can contribute to understanding disease and clinical applications.
Professional alignment (accreditation): Harvard identifies HDRB as an undergraduate A.B. concentration within Harvard College rather than a separately professionally accredited degree. The concentration is academically aligned with preparation for medicine, biomedical research, graduate-level biological research, and other life-science fields.
Reputation (employability/rankings): In the QS World University Rankings by Subject 2026, Harvard is ranked #1 globally for Biological Sciences; QS also places Harvard #1 globally for Life Sciences & Medicine in 2026. These are university/subject-level rankings rather than rankings specifically assigned to the HDRB undergraduate concentration.
Students in Harvard’s Human Developmental and Regenerative Biology (HDRB) concentration gain practical research experience throughout their undergraduate years, with hands-on laboratory work integrated into the program and independent research required as part of the concentration. Students can work in Harvard laboratories studying human development, stem cells, regeneration, disease mechanisms, and related areas, with access to specialized research infrastructure across HSCRB, Harvard Medical School, and the wider Harvard research ecosystem.
The program’s practical opportunities are particularly research-focused:
The Human Developmental and Regenerative Biology (HDRB) undergraduate program at Harvard provides a strong foundation in human development, stem cell biology, regeneration, disease, and modern life sciences. Harvard emphasizes hands-on research throughout the four undergraduate years, with independent research required as part of the concentration, preparing students for research careers as well as medical, graduate, and other biomedical pathways. Harvard officially lists this undergraduate program as a Bachelor of Arts (A.B.), rather than a BS.
Typical career roles: Research Assistant, Laboratory Research Technician, Biotechnology Research Associate, Biomedical Research Associate
: Students can build professional experience through Harvard’s career services, research laboratories, biomedical networks, and life-sciences employer activities:
Further Academic Progression: HDRB graduates can continue into PhD and other graduate-level biomedical or life-science programs, particularly in developmental biology, regenerative biology, stem cell biology, molecular biology, genetics, and related fields. The concentration also specifically prepares students interested in medicine and other health professions, while the required independent research can provide a strong foundation for research-intensive postgraduate study.
