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 trailblazers paved the way for modern computing and smartphones when they created very-large-scale integration (VLSI), the process of combining millions to billions of transistors into a complex digital system on a single silicon chip.

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. Caltech seismologists invented the Richter scale in 1935 to measure earthquake magnitude and also developed its successor, the moment magnitude scale. Previous Next Image Lightbox Discipline-Defining Leaders Kip Thorne (BS '62) and Barry Barish, physicists with the Laser Interferometer Gravitational-wave Observatory (LIGO), were awarded the Nobel Prize in Physics for the first detection of gravitational waves—ripples in space-time—emanating from merging black holes. Bioengineer Pamela Björkman is developing a universal coronavirus vaccine that will provide protection against SARS-CoV-2 variants and other coronaviruses. Alum Leroy Hood (BS '60, PhD '68) invented the automated DNA sequencer, which helped launch the field of genomics and enabled the Human Genome Project. Electrical engineer Azita Emami developed a pressure-sensing eye implant that could help glaucoma patients monitor their condition and prevent blindness. Previous Next Image Lightbox Cutting-Edge Innovation The Center for Autonomous Systems and Technologies (CAST) is developing self-driving robots, including prototypes for an autonomous flying ambulance and drone swarms that will provide support during a natural disaster. Researchers at Caltech showed that neutron star mergers are behind the creation of some heavy elements, such as gold and platinum. Credit: National Science Foundation/LIGO/Sonoma State University/A. Simonnet Caltech's neuroscience researchers have probed the psychology of the stock market, pinpointed neural regions that govern economic anxiety, and identified neurons that alert your brain when you make a mistake. Caltech's Space Solar Power Project (SSPP) was the first to wirelessly transmit power in space, a demonstration of the technology that could one day allow humans to harvest power in space and beam it to Earth. Previous Next Image Lightbox Explore This is Caltech Research Caltech scientists investigate critical questions in science and engineering through high-risk, high-reward, collaborative, developmental research. JPL The Jet Propulsion Laboratory (JPL), founded by Caltech rocket scientists and managed by the Institute for NASA, leads robotic missions to outer space to advance our knowledge of Earth, the solar system, and beyond. Academics Caltech cultivates curiosity and provides its students with a strong scientific foundation through its core curriculum, its commitment to providing research opportunities for all students, and its access to the top faculty in their fields. Community Caltech's students, faculty, postdoctoral scholars, staff, and alumni connect through a shared ethos of collaboration, inclusion, and a passion for science and discovery. Impact Caltech's influence on science, engineering, technology, and society reaches far beyond its Pasadena campus. By the Numbers Caltech at a glance.
