Graduate Admissions
The doctoral program in Microbiology, Immunology and Infection is based in the Department of Microbiology & Immunology and is one of the specialized research and training areas within the Basic Cell and Molecular Biology Division of the Coordinated Doctoral Program in Basic Sciences at CUMC.

The Department of Microbiology & Immunology offers a program of study leading to the Ph.D. in Microbiology & Immunology. You will earn M.A. and M.Ph. degrees in the course of your studies. There is no program leading to a M.S. degree. If you are accepted to the Ph.D. program, you will be given full support for tuition, student health services, and medical insurance. You will also receive a stipend for your personal use, which continues throughout your graduate studies.

Applicants to the doctoral program in Microbiology, Immunology and Infection should have a bachelor's degree or equivalent, an advanced knowledge of biology, and a basic knowledge of chemistry, physics and mathematics. Research experience is regarded very favorably. Recent scores for the Graduate Record Examination (verbal, quantitative and analytical) are required for admission, and it is recommended, but not essential, that an advanced GRE test be taken in biology, biochemistry and molecular biology, or chemistry. Foreign applicants must demonstrate proficiency in English by taking the test of English as a Foreign Language (TOEFL). The department does not impose any cap on accepting foreign applicants. If accepted, they are fully funded by the program. Having their own fellowship is welcomed, but is not a criterion by which their application is evaluated.

You should apply for admission online to the doctoral program in Microbiology, Immunology and Infection of the Columbia University Graduate School of Arts and Sciences at the College of Physicians and Surgeons. All application procedures are available on the Graduate School of Arts and Sciences application guidelines website, including application deadlines.
