Quantitative and Computational Biology
The Program in Quantitative and Computational Biology (QCB) is intended to facilitate graduate education at Princeton at the interface of biology, the more quantitative sciences, and computation. Administered from The Lewis-Sigler Institute for Integrative Genomics, QCB is a collaboration in multidisciplinary graduate education among faculty in the Institute and the Departments of Chemistry, Chemical and Biological Engineering, Computer Science, Ecology and Evolutionary Biology, Molecular Biology, and Physics. The program covers the fields of genomics, computational biology, systems biology, biophysics, quantitative genetics, molecular evolution, and microbial interactions.
An Outstanding Tradition: Chartered in 1746, Princeton University has long been considered among the world’s most outstanding institutions of higher education, with particular strength in mathematics and the quantitative sciences. Building upon the legacies of greats such as Compton, Feynman, and Einstein, Princeton established the Lewis-Sigler Institute of Integrative Genomics in 1999 to carry this tradition of quantitative science into the realm of biology.
World Class Research: The Lewis-Sigler Institute and the QCB program focus on attacking problems of great fundamental significance using a mixture of theory and experimentation. To maximize the chances of paradigm shifting advances, there is an emphasis on studying fundamental processes in biology, such as transcription and metabolism, in tractable model organisms including bacteria, yeasts, worms, and fruit flies.
World Class Faculty: The research efforts are led by the QCB program’s 40+ faculty, who include a Nobel Laureate, 8 members of the National Academy of Sciences, 4 Howard Hughes Investigators, and over a dozen early career faculty who have received major national research awards (e.g., NSF CAREER or NIH Innovator).
Personalized Education: A hallmark of any Princeton education is personal attention. The QCB program is no exception. Lab sizes are generally modest, typically 6 – 16 researchers, and all students have extensive direct contact with their faculty mentors. Many students choose to work at the interface of two different labs, enabling them to build close intellectual relationships with multiple principal investigators.
Stimulating Environment: The physical heart of the QCB program is the Carl Icahn Laboratory, an architectural landmark located adjacent to physics, biology, chemistry, neuroscience, and mathematics on Princeton’s main campus. Students have access to a wealth of resources, both intellectual and tangible, such as world-leading capabilities in DNA sequencing, mass spectrometry, and microscopy. They also benefit from the friendly atmosphere of the program, which includes tea and cookies every afternoon. When not busy doing science, students can partake in an active campus social scene and world class arts and theater events on campus.
Two courses, QCB 515 and COS/QCB 551, are required for all students, as is a Responsible Conduct in Research (RCR) course. Three additional courses must be completed and can be chosen from the following list. Course selections must include at least one course from the quantitative courses list and one course from the biological courses list.
Note: The full course of study must be reviewed and approved by the Director of Graduate Studies (DGS).

Research Colloquium: QCB Graduate Colloquium
QCB Graduate Colloquium is a research colloquium that has been developed for QCB graduate students, usually held on an afternoon during the fall and spring terms. Graduate students have the opportunity to present their research to peers.
All students are required to complete a minimum of three research rotations, with a maximum of four, to explore possible research advisers.
The general examination is usually taken in January of the second year, and consists of a 7 page written thesis proposal and one 3-hour oral session on the student’s thesis proposal.
The Master of Arts (M.A.) degree is normally an incidental degree on the way to full Ph.D. candidacy and is earned after a student successfully passes the general examination. It may also be awarded to students who, for various reasons, leave the Ph.D. program, provided the student has completed all coursework, pre-generals requirements, and the written portion of the general examination.
At least two semesters of teaching are required for all graduate students. Students will typically teach in the fall and spring terms of their third year. Teaching assignments are made by the Director of Graduate Studies, and students are notified of assignments in the summer of their second year.
Research progress is overseen by a thesis committee selected by the student after passing the general exam.
The dissertation and final public oral exam (FPO) are required for all Ph.D. students. All students must write and successfully defend their dissertation according to Graduate School rules and requirements.
