How should I compare Johns Hopkins and Princeton for undergraduate chemical engineering?

The biggest practical tradeoff is that Johns Hopkins offers a more explicitly biomedical, professionally oriented Chemical and Biomolecular Engineering path, while Princeton’s Chemical and Biological Engineering program pairs chemical engineering with a smaller, highly residential undergraduate environment and a strong culture of faculty-guided independent work. Both can provide meaningful lab access early, but Hopkins’ proximity to its medical campus makes it especially compelling for biomaterials, drug delivery, bioprocessing, and engineering connected to human health. Princeton can be particularly attractive for students who want to connect chemical engineering to fundamental science, energy, sustainability, catalysis, or biological engineering.

At Johns Hopkins, look closely at the Chemical and Biomolecular Engineering curriculum, the research groups you could realistically join, and how easily undergraduates participate in work across engineering, medicine, and public health. The Baltimore location also creates access to hospital-adjacent research and regional biotech opportunities. Its larger research ecosystem may offer more distinct lab niches, though students need to be proactive about reaching out to faculty.

At Princeton, the Chemical and Biological Engineering department is small enough that advising and faculty relationships can feel unusually close. The program benefits from Princeton’s emphasis on independent research and its substantial senior work, and undergraduates can pursue research in areas such as soft materials, bioengineering, energy, and molecular design. Its liberal arts distribution requirements and residential campus can make the four-year experience feel broader and more cohesive than a narrowly preprofessional program.
