How do CMU and Caltech compare for undergraduate research opportunities?

The main tradeoff is breadth versus proximity: Carnegie Mellon offers a much larger computer science research ecosystem and more specialized labs, while Caltech’s very small undergraduate population can make faculty relationships and early lab access feel more direct. At both schools, motivated undergraduates can begin research well before senior year, but neither makes every position automatic.

CMU is particularly strong for students who want choices across areas such as AI, robotics, machine learning, systems, human-computer interaction, language technologies, security, and computational biology. Students commonly find opportunities by taking advanced courses, contacting professors whose work matches their interests, and using departmental or university research programs. The scale is a real advantage, but it also means a student may need to be proactive and persistent when approaching busy labs, especially popular CS groups.

Caltech has fewer CS faculty and fewer distinct research groups, but its undergraduate-focused culture is unusually research-intensive. The Summer Undergraduate Research Fellowships program, commonly called SURF, gives students a structured way to propose and conduct faculty-mentored summer projects. Because classes and departments are small, students may have more frequent contact with professors and graduate students, though finding a precise match can be harder if your interests are outside Caltech’s comparatively narrower set of CS specialties.

For a student committed to exploring many possible CS subfields, CMU provides the deeper menu of labs and collaborators. For someone drawn to a close-knit, science-heavy environment and the prospect of sustained mentorship with a small faculty community, Caltech can offer more immediate access. On research access alone, Caltech may feel easier to enter early; on the range and depth of CS research available over four years, CMU has the edge.
