Caltech
This is Caltech

Caltech is a world-renowned research university that develops cutting-edge technologies, addresses fundamental scientific questions, and pursues solutions to the world's greatest challenges. The Institute is defined by its people: faculty, students, postdoctoral scholars, alumni, and staff who collaborate across disciplines, launch new fields of study, and expand human knowledge.

Transformative Research

Caltech neuroscientists have created neuroprosthetics that can interpret the intentions of patients with paralysis, allowing them to control assistive devices.
Automobile exhaust and smog covering the city of Los Angeles.
Caltech researchers discovered the link between automobile exhaust and smog, and the existence of toxic lead in many materials around the world, both of which prompted the development of environmental and consumer protections.
