BA in Chemistry & Physics

The joint Chemistry & Physics major at Boston University incorporates the core elements of chemistry and physics to enable an interdisciplinary study of the structure and properties of atoms, molecules, and materials. The degree provides a more extensive foundation in physics and theoretical methods than a traditional chemistry major, as well as a robust background in organic, inorganic, physical chemistry, and experimental chemistry techniques. This curriculum, which carefully combines courses in the two disciplines, positions students well for graduate work at the interface of chemistry and physics in fields such as chemical physics, biophysics, molecular engineering, material science, and others. These fields at the interface are central to emerging research directions in quantum computing, quantum materials, molecular electronics, nanomedicine, environmental engineering, among others. The major may also be suitable for students whose career goals lie in medicine. Chemistry & Physics majors will be advised by a faculty member with a strong affiliation to both departments.

Learning Outcomes

Students completing the BA in Chemistry & Physics will have:

  • Knowledge of fundamental concepts in physics and chemistry.
  • Laboratory skills, including in physical chemistry and foundational physics experiments.
  • Foundations in mathematical and modeling methods.
  • Combined theoretical, experimental, and computational skills to apply to real-world problems in molecular science.


All BU undergraduate students, including both entering first-year and transfer students, will pursue coursework in the BU Hub, the University’s general education program that is integrated into the entire undergraduate experience. BU Hub requirements can be satisfied in a number of ways, including coursework in and beyond the major as well as through cocurricular activities. Students majoring in Chemistry & Physics will ordinarily, through coursework in the major, fulfill 16 or 17 units of the Hub requirements, including Quantitative Reasoning 1 and 2, Scientific Inquiry 1 and 2, 2 units of Critical Thinking, 2 units of Research and Information Literacy, 2 units of Teamwork and Collaboration, 1 unit of Creativity/Innovation, 1 unit of Digital/Multimedia Expression, 1 unit of Oral and/or Signed Communication, 2 units of Writing-Intensive Course, 1 possible unit of Writing, Research and Inquiry, and 1 unit of Historical Consciousness. The remaining 9 or 10 BU Hub requirements will be satisfied by selecting from a wide range of available courses outside the major or, in some cases, cocurricular experiences.

Unless otherwise noted, all required courses are four credit hours.
