Columbia University

What you'll study

The PhD emphasises original research in areas that include oral and craniofacial development, oral microbial pathogenesis, biomaterials and tissue engineering, pain and sensory neuroscience of the orofacial region, immunology as it relates to oral disease, and translational approaches to dental therapeutics. In the first one to two years students normally complete core coursework and laboratory rotations to build a rigorous foundation in molecular and cellular biology, advanced microscopy and imaging, quantitative methods and experimental design.

• Core topics: molecular biology, cell signalling, developmental biology, oral microbiology and immunology.
• Specialist modules: biomaterials and tissue engineering, craniofacial genetics, pain mechanisms, periodontal biology and implant biology.
• Research methods: advanced microscopy and imaging, bioinformatics, biostatistics, experimental design and ethics in human and animal research.
• Training activities: laboratory rotations, regular research seminars, journal clubs, teaching assistantships and responsible conduct of research courses.
• Milestones: qualifying (or candidacy) examination, proposal/committee review of the dissertation project, and completion and defence of a written dissertation based on original research.

Entry requirements

Applicants typically hold a DDS/DMD, DClinDent, DPH, MD, MS/PhD in a related biomedical science, or a bachelor’s degree with significant research experience in the life sciences. Selection is competitive and based primarily on research potential and fit with available faculty mentorship.

• Academic record: a strong undergraduate and, if applicable, postgraduate transcript in dentistry, biomedical sciences or a closely related discipline.
• Research experience: demonstrated laboratory or clinical research experience is essential; applicants should describe projects, techniques used and any publications or presentations.
• References: at least three academic or research references who can attest to research aptitude and potential for independent scholarship.
• Application materials: CV, personal statement outlining research interests and prospective faculty mentors, academic transcripts and a research plan or summary.
• English language: proof of English proficiency for international applicants where required by the university (e.g. TOEFL or IELTS).
• Additional requirements: interviews with prospective supervisors and a departmental admissions committee are normally part of the process. Standardised tests (e.g. GRE) may be optional or subject to department policy—check the programme for current guidance.

Career prospects

Graduates of Columbia’s doctoral programmes in dentistry and oral biology move into a variety of research-focused careers. Typical pathways include tenure-track academic positions in dental schools and medical schools, postdoctoral research in basic and translational laboratories, leadership roles in industrial research and development (dental biomaterials, pharmaceuticals, diagnostics), regulatory science, and clinical research roles in hospital or specialised practice settings.

Other career outcomes include positions in public health agencies, non‑profit research organisations, science policy, and entrepreneurship where expertise in oral health, biomaterials and translational research is valued. The programme’s emphasis on rigorous experimental training and mentorship prepares students for competitive grant funding and collaborative research leadership.

Why study at Columbia University

Columbia offers access to a multidisciplinary research environment that combines the College of Dental Medicine with strong collaborations across the medical centre, biomedical engineering, molecular biology and public health. Students benefit from world-class laboratory facilities, core imaging and genomics resources, and mentorship from faculty who lead research in craniofacial biology, oral microbiology and biomaterials.

The university’s location in New York City provides opportunities for clinical collaborations, industry partnerships and engagement with diverse patient populations. Doctoral candidates also gain professional development through teaching opportunities, grant-writing workshops and a wide seminar series, preparing them for academic and translational research careers.
