Molecular and Cellular Biology

The Molecules, Cells, and Organisms PhD program in the Department of Molecular and Cellular Biology provides you with a view of the broad range of the constantly evolving world of scientific experience.

In this interdisciplinary program, you will interact with students and faculty possessing diverse backgrounds in chemistry, marine biology, computational biology, and others. The skills you will learn in your first year include coding, how to write fellowships, and how to give scientific talks to a non-science audience. You will begin bonding with your small cohort of fellow students with an annual trip to Cape Cod to talk science at the beginning of the academic year.

Dissertations students have completed include Characterization of the epigenetic regulator LSD1 as a Druggable Dependency in Treatment of Resistant Melanoma and Circadian Clocks in the Real World: Effects of Dynamic Light Regimes on the Regulation of Circadian Gene Expression in Cyanobacteria.

Graduates have secured positions in industry with companies such as Google, Genentech, and Novartis. Others now have academic positions at many prestigious schools including Harvard, Caltech, Stanford, and MIT among others.

Additional information on the graduate program is available from the Department of Molecular and Cellular Biology and requirements for the degree are detailed in GSAS Policies.

Admissions Requirements

Please review GSAS admissions requirements and other information before applying. You can find degree program-specific admissions requirements below and access additional guidance on applying from the Department of Molecular and Cellular Biology.

Academic Background

Applicants should have a record of introductory courses in chemistry, biology, physics, and mathematics. While the following courses should not be regarded as prerequisites for admission to graduate study, most admitted students have completed these courses as undergraduates:

  • Biology (at least one general course in biology and two terms of biology at a more advanced level)
  • Biochemistry
  • Organic chemistry
  • Physical chemistry
  • Physics (a general course)
  • Mathematics (a basic knowledge of differential and integral calculus). Competence in elementary programming is also desirable.
  • Laboratory in biology, biochemistry, or instrumental analysis.

Statement of Purpose

Describe your reasons and motivations for pursuing a graduate degree in your chosen degree program, noting the experiences that shaped your research ambitions, indicating briefly your career objectives, and concisely stating your past work in your intended field of study and in related fields. Your statement should not exceed 1,000 words.
